I've seen plenty of people ask about it but seems like it doesn't ever get answered.
I hate to be negative about what is on the surface of it a great product but this is hammering the performance on my server and making me think I really shouldn't be using this in a production environment.
Any moments of genius or inspiration greatly appreciated!
Best to clear the UrlHistory table. It is probably because duplicates url parts are stored but it's a hard bug to reproduce. V2 will not have this issue since it's not using the database anymore. Most environments don't have this by the way :)
Sorry you had this issue.
I've cleared the table but am still getting exactly the same issue.
Clear cache by restarting site?
No that didn't work. Still the same issue.
Just wondering if you had any other suggestions for fixing this issue?
I know you mentioned this was difficult to replicate but we seem to be experiencing this on all of our sites using SEO Checker (about 5) - happy to provide additional information or be a guinea pig in trying to resolve as if we can't we will need to remove the package.
Sorry for not getting back. did not receive a notification about the last mail. But would it be possible to share one of the sites (files + db) with me? Then I can run in debug mode. If possible please send an email to firstname.lastname@example.org
