File Uploads Not Finishing

[Warran]

Hi

I am having an issue uploading files via 'Files' fields in my templates. Progress goes to 100% but then goes no further i.e. to the point where you would add the description for the file just uploaded. Attached is a screenshot showing where it gets stuck.

Works ok with very small file sizes but not with larger files such as the 8MB one in the screenshot. The ini file settings are:

memory_limit 128M
post_max_size 32M
upload_max_filesize 32M
max_input_time 360

Hosting provider is adamant it's a CMS issue.

Any help would be appreciated.

Thanks

Check if there is an error on the console, this has happened to me when there is a javascript error parsing the console, sometimes happening when a PHP warning or errors gets attached to the response of the ajax file upload.

Thanks, I'll check that and report back.

I've checked and no errors are being generated in console.

You're on the right track! Adjusting PHP settings should help.

Update: 

I've uncovered the following error:

session_write_close(): Failed to write session data using user defined save handler. (session.save_path: /var/cpanel/php/sessions/ea-php82, handler: write) in <b>Unknown</b>on line <b>0</b>

Any thoughts?
