Versions 3.1.8 and 18.104.22.168 were including the wp_session manager 1.1 library and it was storing the temporary sessions in the WP options table. WP session 1.1 has a bug that caused the sessions rows not to purge automatically.
In version 22.214.171.124, I removed the wp session manager library and made a function to remove the _wp_session entries from the wp options table in the database. So if your site was very busy, there could be many many database entries and WordPress could potentially time out while trying to purge them. Once they are purged, it does not try to purge them anymore and the plugin should function normally.
If this happens, you might have to purge them manually from the sql command in phpMyAdmin
Backup your database first! I take no responsibility for any data loss.
If you have any other plugins that use wp_session, you might not want to do this:
These are the sql commands
You WILL have to change the `wp_options` inside the commands to your actual wordpress options table name
See if there are any wp_session rows to delete:
SELECT * FROM `wp_options` WHERE option_name LIKE '_wp_session%' LIMIT 0 , 50
Take note how many rows are returned, if it is 0, then you do not need to continue.
You might see many rows returned similar to this: (with random sessions ids)
You might also see (or not) rows returned similar to this: (with random sessions ids)
Delete up to 500 rows at once (repeat this command until 0 rows are returned)
DELETE FROM `wp_options` WHERE option_name LIKE '_wp_session%' LIMIT 500
When no more rows are returned, you are done.Do you need help?
