I started having this same issue this week (10/3/23) on the newest version of Spectra (2.7.11). Strangely, only a few pages were affected and I can find no commonalities among them (one includes toolset dynamic content, one includes an imbedded WP form but no toolset blocks). At first it looked like a caching issue because a purge on whichever page was broken would fix it. So the server admin wrote a cron job to purge the whole site cash every hour. But that wasn’t enough to keep visitors from seeing a broken home page occasionally. Then I stumbled upon this support thread, and I rolled back to version 2.7.9, changed settings to put the css and js into the page code and regenerated assets. So far these changes seem to keep the issue at bay. But I don’t think this is the right solution. So I’m hoping for more guidance.
