Re 'age' of installation, it's a modx revolution, I can't remember when I installed it, was a few years ago. I wouldn't call that 'old' myself. I forgot to mention, this is the advanced modx revolution.
Don't know where the "aresource" is coming from, it should be "resource".
That's the question I believe, so the answer is what is missing.
Same for the 'update.php' instead of update.class.php.
The browser cache was a good thing to remind users of, and me, so I cleared cache, and, even better, logged in with a browser I'd never logged into the manager before.
Same results. So the issue can't be the browser cache since that browser had no cache of the manager, though it is a good guess.
Are there other locations in modx core or manager that might have cached files? the update.php seems like a dead giveaway that something cached or corrupted is being used when it shouldn't be. As with the /aresource/ corruption.
Again, one of things I want to figure out is how to fix this in case this ever happens on the live site, if it does, I need to have it running very quickly, and since it clearly can happen, and has happened, what I need to figure out is how to fix it.
What we know so far:
1. The core/cache/ has been cleared, both via control panel and direct rm -fr core/cache/*
2. The browser caches have been cleared, and a fresh browser has been used
3. The issue is only occurring on my local dev version
4. I've imported the live db sql several times to the local dev version, which means that the db tables are identical, except for the adjustment to the core path in the workspaces table required when moving it. Though there could be a table in there with a changed name left over in theory.
5. aresource and update.php do not occur in the actual files of core or anywhere else. Which does really suggest a caching issue, only as noted, the caches of browsers/modx have been cleared, repeatedly. Well, it does occur in the log data after the error happens, of course, but that's it.
