WordPress 4.3 – Widgets Won't Update

Have you tried:
– Flushing any caching plugins you might be running, as well as server and/or browser caches. Also, any op cache or content network cache, as well as Cloudflare, clear those caches.
– deactivating ALL (yes all) plugins temporarily to see if this resolves the problem (plugin functions can interfere). If this works, re-activate them individually (one-by-one) to find the problematic plugin(s).
– switching to the unedited default Twenty Fifteen theme for a moment using the WP dashboard to rule out any theme-specific issue (theme functions can interfere like plugins).

Thanks Tara,

I had gone through the plugins one-by-one but had skipped a couple of “essentials” that I’ve been using for a while. Your reply nudged me to pull the trigger and deactivate them all, which temporarily solved the problem. So after reactivating them all (problem returned) I tested the “essential” plug-ins and discovered JetPack was the culprit.

I would still like to run JetPack, so I tried uninstalling some of the features I didn’t use very often – including the ones specifically related to widgets. That didn’t solve anything.

So for now I’m just going to temporarily disable JetPack, make my widget edits, then activate it again. Not the best solution, but hopefully JetPack will have an update to fix the bug soon.

Thanks again!

I may have spoken too soon. I was able to make a couple of edits to my widgets with JetPack disabled, but now I’m having trouble making edits – regardless of whether JetPack is enabled or not.

I’m also finding that WordPress is logging me out very frequently. I used to be able to stay logged in for a day or two or three before I was asked to verify my credentials. Now it’s happening ever 5 minutes.

Tara – I’ve been able to make most of the changes needed to my widgets by deactivating nearly every plugin, making the changes, then reactivating them. I’ve gradually been able to narrow my list of plugins that need to be inactive to make changes, but haven’t been able to single out one or a couple that are acting up.

But, after a few rounds of this, I’m now getting this error when I try to make any change in my dashboard – like updating a widget or adding something new to the menu:

Fatal error: Allowed memory size of 104857600 bytes exhausted (tried to allocate 3196609 bytes) in …wp-includes/functions.php on line 384

Have I just exhausted my server by attempting so many changes? Is there some easy way to clear out the exhausted memory and start fresh?

I saw some entries and outside blog posts talking about upping the memory limit in your php.ini file from 32M to 64M, but mine is already at 90M (probably set thanks to some tooling around my host did a year or so ago).

Thanks for any input.

Try increasing to 128M or 256M
Here is a useful codex guide: increasing memory available for php.

Thanks Tara – My host helped me do that and everything seems to be working now. It even seems to have solved my issue with updating widgets!

You are welcome ??
