I should have turned that off, but left disk caching on.. and seen if the errors remained.

I might do that. Then switch back for the performance boost

For what it’s worth… that setting WAS enabled….
Optimize disk enhanced page and minify disk caching for NFS

that WAS on. I guess b/c I’m not on disk enhanced any more, it’s not valid?
I unchecked it anyway

Yes i’m using FPM

OK this is strange…. still performing more checks.
I contacted my host (I’m on a VPS) and asked if I was considered a shared server, b/c I was using disk based cache.. I wondered how many resources I shared though, and if disk was one. Turns out, I’m not, I have dedicated resources.
I did some research, I had zend:opcache turned on in W3TC. I wanted to try moving from disk based to dedicated server…. in W3TC….
but I could not select any options for caching on a dedicated server.

I found that APCu was not installed on my system. I installed APCu. I rebooted. Changed all caches to use APCu

The errors APPEAR to be gone!
the site is faster. In fact, I don’t see ANY errors in the error_log any more.
very strange!
But that’s a good thing.

Also my GTMetrix score (which used to be an A) and fell to F (15%) is now back up near B.

Strange that it was disk based caching causing this? Not sure… but I’m going to keep an eye on the logs.
Thanks so much for assisting me in troubleshooting this!
Does this solution point to anything that was set wrong?
It definitely is clear in the logs.. I keep moving around the site, but have no errors

I ran the apache config to see what modules are installed.
In my W3TC compatibility checker it shows not installed brotli, memchached, memcache, redis. openbasedir and zlib compression show as off. ssh2 not installed

then we get to not detected:
mod_deflate: Not detected (required for disk enhanced Page Cache and Browser Cache)
mod_env: Not detected (required for disk enhanced Page Cache and Browser Cache)
mod_expires: Not detected (required for disk enhanced Page Cache and Browser Cache)
mod_filter: Not detected (required for disk enhanced Page Cache and Browser Cache)
mod_ext_filter: Not detected (required for disk enhanced Page Cache and Browser Cache)
mod_headers: Not detected (required for disk enhanced Page Cache and Browser Cache)
mod_mime: Not detected (required for disk enhanced Page Cache and Browser Cache)
mod_rewrite: Not detected (required for disk enhanced Page Cache and Browser Cache)
mod_setenvif: Not detected (required for disk enhanced Page Cache and Browser Cache)

Looking through these, I see some actually ARE turned on in the config. Some aren’t listed. Some aren’t on. mod_env is not clicked to installed. mod_ext_filter is not clicked installed. i don’t even see a mod_mime. I see mod_mime_magic. the last 2 aren’t shown either.

I removed those lines. The theme still works and things look good. I checked performance and site performance is actually better according to GTMetrix.

The errors continue though.
I disabled the URL re-write. When I do that, the theme breaks. Basically at that point, it becomes a text based website… all the images disappear, everything is left justified text. Very odd.
I turned the rewrite back on, and the theme functions again.

What should I look for in httpd.conf?

Any ideas? Still struggling with this one.

As for these rules, the hosting provider did not add them… and I did not. I’m assuming the plugin did?
RewriteCond %{HTTPS} off
RewriteCond %{HTTP:X-Forwarded-SSL} off
RewriteCond %{HTTP_HOST} ^ravensreelsalmanac\.net$ [OR]
RewriteCond %{HTTP_HOST} ^www\.ravensreelsalmanac\.net$
RewriteRule ^/?$ “https\:\/\/ravensreelsalmanac\.net\/” [R=301,L]

I disabled W3TC and the errors go away.
I re-enabled W3TC
Then…

Disabled Page Cache, still have errors.

It seems the errors go away when I disable Minify.

There are no errors w/ Page Cache enabled, and minify disabled.

Is there a way to determine which plugin is doing it? Or is it usually the theme

This worked perfectly. The order came right back, and I was able to complete it. Thank you for the super fast reply and super rapid fix! Much appreciated!

I have not done that yet.. but I’ll try it if it happens again.

Same thing has happened to me 3 times already too… if I can get into the site and purge the cache, it works again.

I should say, that the site itself does not crash… the site keeps working. I just get that error when trying to get to /wp-admin

To get in, I use the WP app on my phone, deactivate W3TC.
At that point I can get into WP-Admin.
Log in, restart W3TC.. purge all caches.
Things are then fine for a while.

I had similar issues.. also after uploading images it would loop until it crashed.

The work around I found… when this happens….
1- go to a different PC. It’s a cache issue.

2- or if you’re like everyone else in the world and can’t get a new pc every time this happens…if using chrome, go to history. Delete all browsing data for the last 24 hours including cookies. Restart browser. Fixed. I had the same issue and workaround with ie and edge browser

I also reported that my pagination settings were not being retained. I’ve seen others say that also. I keep my install fairly much at the default…. but I do like all pictures on one page (no pagination). every time i set that… if i disable and re-enable the app… it resets to default (20 images / page)

So it actually is possible..
if you want to copy existing files to a new gallery…
Go to Manage Galleries. Create a new, blank gallery.

Now go to the gallery w/ the original files.
Mark the checkbox for all the pictures you want to move.
At the top, on that action drop-down… select Copy To. and hit apply
now a dropdown of all the galleries comes up. Scroll to the bottom for the new blank gallery you created.

Or copy them to whatever other gallery you want if the new destination(s) already exist.
