There have been many changes made to the core code of the addon, so you shouldn't experience any issues in the new version.

However, if you still encounter any problems, you can request a refund.

The developers attempted to install Query Monitor to view the error logs, but Query Monitor fails to load. This should be a server-side issue.

Therefore, we kindly request you to create a development/staging copy of your website on a sub-domain, verify the presence of the problem, and then send us the admin details. You can use Duplicator to create this site.

Additionally, please provide FTP access to the staging website.

When I select an image larger than about 2mb it acts like it working up in the corner, the image is uploaded to the media library and then it doesn't attach.

When I go into the media library you can see the image uploaded. (the last two images). Notice the same image uploaded into my library from another user over and over again. This is because he kept trying to get the image to attach to his post but it would not.

Please leave a screenshot of the settings page where we can see the value of the option.

Additionally, confirm that you've deleted the caches once the value of the option is changed.

The developers have checked your website and currently don't find any issues. I've asked them to upload the large image as well.

For further support, they requested the UL example of the comment with missing images.

We'll check and get back to you ASAP.

Please send the admin login details to infogvectors.com email address. I'll ask the developers to check the issue for you.
