Troubleshooting

Upload limits

File upload size and quantity limits are fix in your server's php.ini. If you have a problem uploading a file in your form, get-go try uploading the aforementioned file on the WordPress → Media Library. If you lot see the same error here, and so you are facing upload limits. You (or your host) may demand 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 tin 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 past the file uploader, even though the code is there to process it.

The nearly probable cause is a plugin or theme disharmonize. Start by checking for a conflict.

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

File upload "-1" error

If y'all're seeing a "-ane" fault when trying to upload a file on your form, this problem is most often related to a plugin or theme conflict. Generally, we accept seen cases where a security plugin is causing this trouble. To troubleshoot this, start by finding the source of the conflict.

Uploaded file could not be moved

If you're seeing the "Uploaded file could not be moved to" mistake message, this problem usually ways that at that place is something wrong with the permissions on your site at a server level.

To troubleshoot this, start by post-obit the steps beneath.

Effort to upload the file in the WordPress → Media Library. Do you come across the same fault? If so, please contact your web host.
If the upload is successful, alter the binder permissions of the uploads/formidable folder, and each of the numbered folders inside it to 755.
If the upload nevertheless fails and regular WordPress uploads are successful, open a ticket and so our team can help investigate.

File upload "0 b" value

If you encounter a 0 b message when uploading a file to your course, you may have added an wrong default value.
File upload 0 b value
When setting a default value, you can either apply a file from the media library or use a file from a previous entry.

Disable scaling in images

In WordPress 5.three, users are immune to upload big image files. It will be automatically scaled downward one time the paradigm tiptop or width is to a higher place the threshold value of 2560px.

To disable the scaling, y'all could apply the snippet below.

add_filter( 'big_image_size_threshold', '__return_false' );

File blazon is not permitted for security reasons

If yous have already set up your site to allow extra file types similar XML, it may render a "Deplorable, this file type is not permitted for security reasons" error message. To ready this, go to the wp-config.php file and add the following code snippet above the line:
/* That's all, cease editing! Happy blogging. */

define('ALLOW_UNFILTERED_UPLOADS', truthful);

Unsupported file type

If you're already using the code snippet to allow extra file types, merely your server still doesn't recognize your file type, you may apply the expected plain/text mime type.

For instance, instead of using the expected mime blazon for a Pace file blazon:

$mimes['stride'] = 'application/Stride';

Use the expected mime type to apparently/text for application/Footstep files instead.

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

This isn't unique to STEP files simply could employ to other file types like MP3 file uploads.

503 error

If yous encounter a 503 mistake while uploading a file, the PHP ImageMagick module could be the upshot. Disable ImageMagick and try GD on your server.

If you would similar to let file types than are not allowed in WordPress by default, you'll need some custom lawmaking.

add_filter('upload_mimes','restrict_mime'); part restrict_mime($mimes) {     $mimes['mp4'] = 'video/mp4';     $mimes['csv'] = 'text/csv'; //allow csv files     $mimes['avi'] = 'video/10-msvideo'; //add together avi     $mimes['mov'] = 'video/quicktime'; //add mov     $mimes['epub'] = 'awarding/epub+goose egg'; //add epub     $mimes['ai'] = 'awarding/postscript'; //add ai     $mimes['eps'] = 'application/postscript'; //add together eps     $mimes['xml'] = 'application/xml'; //add xml      return $mimes; }

This is a WordPress filter (not Formidable). You tin can detect more than information on this filter in the WordPress codex.
