Compatability issues with Litespeed?

Are there any pending updates on your server at the moment?

I don’t believe so. An ongoing update over at least the last 6 days (see below) seems unlikely. Also seems unlikely because I received no notice from my hosting provider, other than a 15 minute outage notice a few days before the switch.

I just checked my plugins, and EUM is doing (part of its job): a couple of plugin auto-updates have occurred since their switch the Litepeed 7 days ago: Yoast 6 days ago, and WordFence 1 hour ago. However, no “background updates have completed” emails in either case.

Shall I verify with my hosting provider?

I would check with them yes and figure out why emails are no longer sending. You may need an SMTP plugin.

hmm…?

The expected Easy Updates Manager emails are sent from the same email address as any other notification emails, <[email protected]>

For example, WordFence sends me emails every time I log in to WordPress. I tested this just now, and it works fine.

Why would I need an SMTP plugin all of a sudden? This seems like an EUM bug to me, wouldn’t you agree?

I just thought of something, this might be relevant since I believe the issue is Litespeed not handling plugin auto-updates properly. So not a plugin bug, but a workaround needed to get the plugin to work with Litespeed. Case in point:

As mentioned, I use the WordFence plugin. The day after my host switched to Litespeed hosting, ** Wordfence auto-update stopped working **

I received a message with instructions on how to fix, see https://www.wordfence.com/help/advanced/system-requirements/litespeed/

I implemented the suggested .htaccess modifications, no further problems since then.

In the same article, they also talk about bypassing the LiteSpeed “noabort” check: If you are certain that your host uses LiteSpeed and that “External Application Abort” is set to “No Abort”, you can enable this option so that Wordfence will skip checking for “noabort” in .htaccess.

Hope this helps?

@clg87,

EUM at this time doesn’t send out any emails. It’s WordPress that does.

We’ve had some reports of EUM not working properly with WordFence, but haven’t been given any reproducible steps.

If you can oblige with what we can do to duplicate the issue, we will file an issue for WordFence and work on better compatibility.

Thank you. My gut tells me the issue is Litespeed, not Wordfence. Reasons for my hunch is the Litespeed timing I explained in my previous post. But I don’t have the deep technical knowledge you and your team would, mine is just a hunch. In any case, here is how I would troubleshoot the issue:

Run two identically configured WordPress environments on two servers, one Litespeed and one Apache. WordPress latest version, Plugins all latest versions of EUM, Wordfence, and a couple of random plugins that are known to update often (ex. Yoast, Smush, etc). Wait a couple of days or so until a plugin(s) is updated by EUM. Expected behaviour is correct updating of apps. Suspected (“hunch”) behaviour will be EUM email updates from Apache but not from Litespeed.

A quick word on Wordfence: after switching from Apache to Litespeed, it was wordfence that provided instructions the next day on how to modify .htaccess to ensure wordfence woukd run in the Litespeed environment. I provided a link to that explanation in my previous post.

Thanks for investigating and if could share your findings, I’d be very interested.

PS: I did not know that it was WordPress sending out autogenerated emails (instead of individual plugins), so that is good to know. In that case, I am having no auto-update problems with the EUM plugin. I have just stopped receiving the related email notifications.

Looks like the problem is resolved. Coincided with a WordFence plugin updates. Looks like it was WordFence after all! Marking this thread as resolved, thanks for the help ??
