I have a big problem. I was just notified by a site owner that styles are broken in multiple places. Is there a wide spread issue? Looks like many hours/days of repairs are needed. Templates are not showing styling. Archives are not showing styles. Custom menus, etc. Custom post types and archives are not showing styles.
Could you please check with " Siteground Optimizer" support and check with them if the issue belongs to them we can't do much here but if its related to Toolset we can dig a bit further.
I spent a lot of time with Siteground support. Ended up deactivating Siteground Optimizer and removing dynamic cache with .htaccess. The styles would not return. example page. enlace oculto
I added the GeneratePress code you recommended as well. I cleared ever cache I could find, cleared dynamic, memcache, etc. Siteground said there must be some other kind of cache blacking the styles. Here is the dev tools screen shot. enlace oculto
The identical staging area (same settings) shows the styles as expected. (SGO is also active on this site) enlace oculto Here is a screen shot of styles. enlace oculto
That is really strange that its working on the staging site and not on the production site. Do you have any blocks or do you see any Javascript error on your browser's console.
