@moderator…

Sorry… thought I did!

Does the notice only show in the logs or also on a page somewhere?

It’s only in the logs… which, I know, as a general rule, aren’t a huge issue, but these warnings started showing up when the website started crashing. The website is returning a 500 error, about 50 times per day (or more). Naturally, I’m going through all the logs, to figure this out, because, other than plugin updates, I haven’t added or removed any plugins, nor have I modified the theme/design.

I started out by scanning the website, with Sucuri, and it gets a clean report!

Who’s the host?

websynthesis.com

Hmm, looks like I missed your last reply, sorry.

If you update to EDD 1.9.5, I bet the issue goes away. There was a bug in 1.9.4 and earlier that caused thousands of rows to get create in the wp_options table.

Go into your database and look at the wp_options table. Delete any and all rows that have a name that matches “wp_session”.

By “name” do you mean “option_name” and by “wp_session” to you mean “_wp_session”

I have this same problem using version 1.9.6

I just ran into this problem. I updated EDD and in MySQL ran the query

delete from wp_options where option_name like '_wp_session%'

The wildcard accounts for both _wp_session and _wp_session_expires

Thousands of rows? Wouldn’t this be better handled by an update?

Perhaps. I’m just here letting you know that I ran into the same problem as you did, and a way to repair it so that the wp_options table is not so bloated (mine was 250+ mb!).

Maybe Pippin will provide an update, but I’ll also bet he’s hesitant (from a liability perspective) to include script that deletes thousands on thousands of rows.

I’m not sure what to tell you. Do whatever you’re comfortable with. I’m only sharing what worked for me. Good luck.

Actually, after writing this post I see that 3568 rows that match ‘_wp_session’ have been created after removing them an hour ago.

Seems that the bug still exists.

Well, the update that should come to fix this should also delete the unnecessary database data.
