I'm with a very serious problem.
Some information disappears after being published. Not exactly at the moment, but it shows up for a few minutes and then disappears.
This does not happen with titles or content, only with custom fields, menus and images (maybe others, but this is what I could identify so far). I'm using ACF PRO, but deactivating it does nothing to solve the issue
The images are cached by Jetpack, so on that side the site works for the moment, but the rest I have no idea why it can be. One thing with images: they show up in media library for 20 or 30 minutes, maybe one hour. After that, they turn into the default grey icon and are gone away. Also, images have their post_thumbnail sizes created. However, on many images the original image isn't uploaded to
wp-content, just the thumbnail sizes. This behavior is not consistent: sometimes it happens, sometimes it doesn't happen.
I already tried activating / deactivating themes and plugins and nothing. Obviously I deactivated cache. I added
max_vars to 10000, nothing (however, I did this in
wp-config.php, I can't edit
htaccess at all).
I'm almost sure it's something from the database, or from the server because it's like there's a kind of giant cache that disappears. There was a person working but he disappeared from the face of the earth and now I do not know what to do.
For what it's worth: I can not edit the
htaccess file, whatever I do it gives me 500 error. But I can generate it from Permalinks
