?? I’m sorry to hear that. I understand. I’ve narrowed down the problem to how the plugin deals with sessions. It’s not a workable solution for high traffic sites. I know how to fix it but haven’t done it yet. I’ll be sure to update you when it is fixed.

Are you saying it worked for a few days after uninstalling it and then crashed again without my plugin installed? That doesn’t seem to make much sense. The fix for the cleaning out the bloat from my plugin is:

DELETE FROM wp_options WHERE option_name LIKE "_wp_session%";

Note: this will delete all the session records from the table. My plugin uses a library that other plugins may use as well so it could clear other sessions as well but since they are meant to be transient, it shouldn’t be a big deal.

I think the problem with dismissing was due to browser cache. I forgot to update the version stamp on it. Whoops! ??

Regarding the customizer, I think I’ve fixed the problem with that in version 1.42. Thanks!

Since this post I’ve published a few more performance updates. It hasn’t resolved it yet for another user but I’m still working on trying to figure out where exactly the lag is coming from.

I’ve updated the plugin to version 5.1. I don’t know for sure that this will solve the problem. I’ve reduced the lifetime of the sessions and upgraded the session manager to the newest version. Could you update and see if it resolves the problem?

Hi –

I’m published an update which should remove that debug notice! Sorry about that!

Hm – these rows are added by the session manager which keeps track of user’s sessions so that they are consistently shown the same titles. How many unique visitors does your site get daily?

I think you may not be looking in the right place. There should now be a “Add a Title” link underneath your titles in the post page.

Wow – that is certainly something that I will fix. Could you provide a sample of the lines that are being written?

I’m not quite sure what you are asking… you pick all of the titles yourself. It doesn’t generate them for you.

It should be able to help both older and newer posts. However, it’s probably going to help newer posts more because they will probably have higher exposure on your site than older posts.

It will find the correct article, regardless of the title that is being shown. It may not be the same title, though. For example, if you are testing Title A and Title B and Google indexes the article with Title A, a user may click on it and see Title B. There isn’t a good way around this.

Yes, there is a setting that determines how long before the plugin chooses the best title and deletes the other.

Yes, depending on how often the plugin recalculates the title probabilities, the plugin will take some extra server resources – though keeping the setting at 30 minutes+ should be acceptable for more sites.

I won’t quote you on that one… ??

I just published version 4.3. I think this will resolve the crash you just experienced. Please give it a shot!

You’re welcome! Mind if I quote you on that? ??

I’ve published a new version of the plugin (4.0). Please try it and see if it resolves the problem.

Also, I was thinking that this could be due to caching. You may want to try setting the plugin to use javascript in the settings and see if that resolves it.

Cheers!

Hm… I think I have a guess as to what the problem is. I’ve noticed in some other installations that something prevents the plugin from starting a session. If the session doesn’t start, then it can’t track who has seen what. Depending on how verbose your server’s logs are, you may see something like “session_start(): Cannot send session cache limiter – headers already sent” in them. I will need to find another solution.
