Version 1.1.0 of WP Redis causes the page list on sites running WordPress 5.5 to timeout

[lukecav]

The fix was to roll back to version 1.0.1 of WP Redis using WP-CLI.

wp plugin update wp-redis --version=1.0.1

The page list in wp-admin would timeout and would not load with WP Redis version 1.1.0 active on the site.
Not sure if the issue is being caused by?
#287

Thanks for the report, @lukecav.

I'm not able to recreate the problem. Could you share more details about the site (plugins, amount of data), or steps I can follow to reproduce?

Hi @lukecav,

This isn't quite enough information to go on. I'll need enough information to reproduce the issue, or you'll need to do a bit of debugging to identify the root cause.

[lukecav]

None of the other active plugins were causing the issue on the page list not loading in wp-admin. Posts and postmeta data levels were not even that high on the site. The same issue happened on another site as well.

[lukecav]

wp_posts 53.5MB
wp_postmeta 111.6MB

[danielbachhuber]

None of the other active plugins were causing the issue on the page list not loading in wp-admin.

Did you try leaving WP Redis active, deactivating all other plugins, and then activating each plugin one by one to see which introduced the slowness?

[lukecav]

Yep, I did and none of the plugins being activated one by one resolved the issue for the page list in wp-admin not loading.

[danielbachhuber]

Ok.

1. When you say "Pages list", what part of the UI are you referring to?
2. Can you enable WP_DEBUG and let me know of any errors you see?

[lukecav]

1. Pages > All Pages /wp-admin/edit.php?post_type=page
2. Yep will do.

[lukecav]

Waiting to be able to enable the WP Redis plugin again and enable debugging on the customer's site to get the info.

Please try to use 1.1.1 version, there were some fixes (today, after your last comment) about multiple keys caching, not sure if they fix your problem, but i think it's worth to try.

[lukecav]

@stavultras
Version 1.1.1 version fixed the issue on the site.

@lukecav good to know, thanks :)

[danielbachhuber]

@stavultras Double props to you — thanks again!
