Troubleshooting

Upload limits

File upload size and quantity limits are set in your server's php.ini. If you have a problem uploading a file in your form, commencement try uploading the same file on the WordPress → Media Library. If you lot meet the same error hither, then you lot are facing upload limits. You (or your host) may need to increase the max_file_uploads, max_input_time, post_max_size, and/or upload_max_filesize settings in your php.ini.

In WordPress Multisite, the upload limits can be customized in 'Network Admin' → 'Settings' → 'Upload Settings'.

Server responded with 0 code

When ajax requests are fired in WordPress, 0 is returned when the request isn't processed. We have seen cases where 0 is returned by the file uploader, even though the code is there to process information technology.

The most likely cause is a plugin or theme conflict. Start by checking for a conflict.

If the trouble continues with all other plugins disabled, in that location may exist an issue with your server settings. In some cases, this happens when there a page is loaded with a different URL than the one set every bit the site URL in the WordPress Settings. To solve the trouble, you will need to add a redirect rule in your .htaccess that will redirect to the correct url. This is also better for SEO.

File upload "-1" mistake

If you're seeing a "-1" fault when trying to upload a file on your form, this problem is most often related to a plugin or theme conflict. By and large, we have seen cases where a security plugin is causing this trouble. To troubleshoot this, start past finding the source of the conflict.

Uploaded file could not be moved

If y'all're seeing the "Uploaded file could not be moved to" error message, this problem usually means that there is something incorrect with the permissions on your site at a server level.

To troubleshoot this, kickoff by following the steps below.

Try to upload the file in the WordPress → Media Library. Do yous see the aforementioned mistake? If so, please contact your web host.
If the upload is successful, change the binder permissions of the uploads/formidable binder, and each of the numbered folders inside information technology to 755.
If the upload still fails and regular WordPress uploads are successful, open up a ticket so our team can help investigate.

File upload "0 b" value

If you meet a 0 b bulletin when uploading a file to your form, you may have added an incorrect default value.
File upload 0 b value
When setting a default value, y'all tin can either use a file from the media library or employ a file from a previous entry.

Disable scaling in images

In WordPress 5.iii, users are allowed to upload large image files. Information technology will be automatically scaled downwards once the image height or width is above the threshold value of 2560px.

To disable the scaling, you could use the snippet below.

add_filter( 'big_image_size_threshold', '__return_false' );

File type is non permitted for security reasons

If you have already set up your site to let extra file types like XML, it may render a "Sorry, this file type is non permitted for security reasons" error message. To set this, go to the wp-config.php file and add the post-obit code snippet above the line:
/* That's all, cease editing! Happy blogging. */

define('ALLOW_UNFILTERED_UPLOADS', true);

Unsupported file blazon

If you're already using the code snippet to permit actress file types, but your server still doesn't recognize your file blazon, you may use the expected manifestly/text mime type.

For example, instead of using the expected mime type for a STEP file type:

$mimes['step'] = 'awarding/STEP';

Utilize the expected mime blazon to patently/text for awarding/STEP files instead.

$mimes['step'] = 'text/plain';

This isn't unique to Stride files but could utilise to other file types similar MP3 file uploads.

503 error

If you come across a 503 fault while uploading a file, the PHP ImageMagick module could be the result. Disable ImageMagick and attempt GD on your server.

If you lot would like to permit file types than are not allowed in WordPress by default, you'll need some custom code.

add_filter('upload_mimes','restrict_mime'); part restrict_mime($mimes) {     $mimes['mp4'] = 'video/mp4';     $mimes['csv'] = 'text/csv'; //let csv files     $mimes['avi'] = 'video/ten-msvideo'; //add together avi     $mimes['mov'] = 'video/quicktime'; //add mov     $mimes['epub'] = 'application/epub+zip'; //add epub     $mimes['ai'] = 'application/postscript'; //add ai     $mimes['eps'] = 'application/postscript'; //add eps     $mimes['xml'] = 'application/xml'; //add together xml      return $mimes; }

This is a WordPress filter (not Formidable). Yous can find more than data on this filter in the WordPress codex.

Foreclose filtering of form uploads

If you would like to prevent the filtering of files that accept been uploaded through formidable forms in your WordPress media library, insert the post-obit code in the 'Code Snippets' plugin or a child theme'due south functions.php file.

add_action( 'pre_get_posts', 'frm_remove_media_filtering', 1 ); office frm_remove_media_filtering () {      remove_action( 'pre_get_posts', 'FrmProFileField::filter_media_library', 99 ); }

Disable dropzone

Disable the ajax uploader and revert to a standard uploader with the code below.

add_filter( 'frm_load_dropzone', '__return_false' );

If you lot want to turn off dropzone on one page, use the frm_load_dropzone claw.

Block dropzone activeness

To disallow uploads that happen before the entry is created, utilize the code snippet below to block the dropzone action.

add_action('wp_ajax_nopriv_frm_submit_dropzone', 'block_dropzone_uploads', 1 ); add_action('wp_ajax_frm_submit_dropzone', 'block_dropzone_uploads', ane ); role block_dropzone_uploads() {     $target_field_id = 996; // change 996 to the file upload field ID     $field_id = FrmAppHelper::get_param('field_id', '', 'post', 'absint' );     if ( $target_field_id === $field_id ) {         wp_die( 0 );     } }

Change the upload field characterization

The default Drop a file here or click to upload message can exist changed with a bit of javascript. Click here to come across an instance.

Translate the upload text

Translation options for the default Driblet a file here or click to upload text are included in the PO file within the plugin. Run into how to translate Formidable for more information.

Add forepart-end file download

If you would like to add front-end file download for uploaded files, meet how to offer a protected file and download file on submit for more information.

Handle file download errors

You lot could handle a redirect with a snippet like this. Note that this may be overwriting over dice handler behaviour from some other plugin.

office custom_die_handler( $bulletin, $title = '', $args = array() ) {      if ( 403 === $args['response'] ) {           wp_redirect( 'http://instance.com/403/' ); // change this URL.           die();      }      _default_wp_die_handler( $message, $title, $args ); } add_filter(      'wp_die_handler',      role() {           return 'custom_die_handler';      } );
