Hi guys,

Every time that I pick a page on the Umbraco Backoffice, it keeps loading for a lot of time (the GetById endpoint keeps loading for more than expected). I checked in the log file and I found this: {"SEOChecker: SEOChecker: Error in UrlRewriteIdProvider for url rewriting","@l":"Error","@x":"System.NullReferenceException: Object reference not set to an instance of an object.

I removed the SEO Checker package from the umbraco solution and everything came back to the normal.

So, can you please take a look on that?

The Umbraco version is 8.5.4.

UPDATE:

I updated the SEO Checker to the new version (2.9.0) and the error issue is solved, however the slow issue keeps. I can fix the slow issue just removing the SEO Checker from the umbraco solution. The umbraco solution where I'm working has 9 languages setup.

Thank you, Ricardo P.
