Admin page not showing any results in the list #13

Closed felixarntz closed 8 years ago

felixarntz commented 8 years ago

The list table on the admin page is not showing any results for me although object cache itself is working properly for me (I tested it by getting a specific post back from Memcached from a PHP script outside of WordPress; this worked correctly).

When I select the Memcached server, it makes an AJAX request, but an empty response is returned so that the table still stays empty.

I'm not sure what causes this, but I can provide any specific details as necessary. It's just right now I have no idea which details that may be since I'm not very familiar with Memcached.

A few things to try:

Check your web server logs for any missing methods or functions.
In the latest master branch, the admin plugin requires the use of the object-cache.php drop-in that comes with Spider Cache. Previous versions worked okay with others, but we were bottle-necked by them and created a few new functions of our own to help. We'll probably send them upstream to WordPress for consideration.
Ensure your versions of Memcache and Memcached are up-to-date. Older versions do not have the dump function that the UI uses to retrieve all of the results.

Hey @felixarntz, any updates here?

I haven't followed up on that issue, sorry. I had this problem on a test site (non-multisite) that doesn't exist any longer, as of now I'm only using the plugin on multisites, and it works correctly there (same server environment).

I can setup a regular site to check for that problem again if that helps.

It's probably Memcache missing.

I added a notice if that's the case, but it's not very helpful. See #19.
