Featured Images Not Displaying for Newer Posts after Plugin Activation

Okay, looking through our Cron events, we found this:

All our images from the last 5 months are breaking every 3 hours even if we reupload them, so this seems to be the culprit? Is there any way to disable this action permanently? I've already disabled all the generate thumbnails checkboxes and turned off "Generate Thumbnails Via WP-Cron" in the plugin settings (see attached screenshot), but this action is still running every three hours. If it's not this one, something else is running at around the same time interval that is messing up all our images.

At this point, it's too late for us to go back to our backup from before we installed this plugin yesterday because of member payments and renewals. The glitch is really damaging our site, so I'm hoping we can get some help for this soon. Thanks!

Hi,
So the tricky part is that this is a Cron problem, and our webhost (Siteground) does not allow Cron to run on any Wordpress staging sites. I've asked them to change that in the past, but it's a pretty firm policy on their side.

I think what we really need is some kind of function or filter that would disable that specific Cron task (wpdiscuz_generate_thumbnails_every_3h). For whatever reason, turning off that option in the WPDiscuz program settings does not disable/remove the task from Cron. We can still see it in WPCrontrol, and it still runs every 3 hours. It might be a plugin conflict or something, but it's very hard for us to pinpoint.

I noticed in your API that there is a similar filter for the Cron task that deletes unattached files ( https://wpdiscuz.com/docs/codex/filters/wpdiscuz_delete_unattached_files/). Is there anything like that for this generate thumbnails Cron task? Or even just a generic function we could put in functions.php to see if it will turn it off?

We can definitely give you admin access to our main site if that would be helpful. Thanks so much for your help!

Hi,
So unfortunately, when we installed the newest version of the plugin, it actually broke every thumbnail on our website, not just the ones from the last 5 months. This was pretty catastrophic since our site has over 700 posts/pages and 3000 paying users who access the site quite regularly.

We then turned off the WPDisquz plugin and were eventually able to fix all the thumbnails by installing a plugin called "Regenerate Thumbnails."

Given that our thumbnails all disappeared so quickly after the WPDisquz plugin was activated, my guess is that it is doing something to all the thumbnail entries in the wp_posts or wp_postmeta tables of the database that is breaking everything. I don't know if this is some kind of theme incompatibility with the thumbnail sizes used by our theme (the7)? I didn't see any actual thumbnail files missing in our Uploads folder, and I don't imagine it could have actually regenerated that many thumbnails within a minute or two of the plugin's activation.

I'm not sure how to move forward at this point. We're almost afraid to reactivate the plugin since we know it will immediately break all the images on our site. I think the only way is if we had some kind of function or filter that would force disable the wpdiscuz_generate_thumbnails_every_3h task that we could add to functions.php or something like that. It's unfortunate that it runs as soon as the plugin is activated. Since the thumbnail regeneration is not working on our site, we really need to be able to use your plugin without it. Everything else on the plugin seems to work great, and we love the comments features and media uploads.
