==== Errors in console and logs ====
The error message is as follows Uncaught Error: Call to a member function getSite() on null in \/var\/www\/xxxxxxx.org\/concrete\/src\/Entity\/Site\/SiteTree.php:41\nStack trace:\n#0 After some research, I found that this is happening because the locale was returned as null to getSite function. Not sure why this is happening. Could please let me know the reason this could be happening so that I can check on those possibilities as well
Exception logged:
/var/www/xxxxxxx.org/application/config/doctrine/proxies/__CG__ConcreteCoreEntitySiteLocale.php:8 Declaration of DoctrineProxies__CG__\Concrete\Core\Entity\Site\Locale::setSiteTree($tree) should be compatible with Concrete\Core\Entity\Site\Locale::setSiteTree(?Concrete\Core\Entity\Site\SiteTree $tree = NULL) (2) This was an exception I received before getting "Uncaught Error...."
I found some references related to this error
concrete5.org/community/forums/customizing_c5/… Where the user describes the number of possibilities. But would need to help unerstand the reason why should I be checking the server settings for my error and what should I be looking for
The site has a multilingual sitemap but none of them works. The site is currently at version "concrete5 - 8.5.0".
Whatever related issue I was able to find were with earlier version of concrete 5 and the changes that were committed to resolve the issue already exists in this version
Some of the URLs that I found https://www.concrete5.org/community/forums/usage/cant-load-sitemap-error-msg-inetrnal-server-error https://www.concrete5.org/community/forums/customizing_c5/sitemap-no-longer-works-shows-and039internal-server-errorand039/ https://github.com/concrete5/concrete5/commit/2cf69ac90a8c8d1c7a451c9a82badf358cc74a1a
None of them points our the reason of this issue. It would be really appreciated if somebody can help me out the direction to figure out the reason of the issue and solution for it.
