Sitemap entry not found

Dear Grav community,

I am working on our website https://netilion.endress.com/ running on Grav ( v1.7.34 )
and since a few month our sitemap returns an error from Grav:

https://netilion.endress.com/sitemap

Server Error
Sorry, something went terribly wrong!

0 - Class “Grav\Plugin\Sitemap\SitemapEntry” not found

For further details please review your logs/ folder, or enable displaying of errors in your system configuration.

The funny thing is that the issue only occurs online, locally the sitemap works perfectly.

I’ve updated all the plug-ins including sitemap plugin, but nothing helps. The sitemap still doesn’t work.

Any ideas what could be wrong?

Thank you so much.
Much love
Nico

Hi all, the solution is following.
After a certain Grav CMS update, Grav changed the filename: SitemapEntry.php to sitemapentry.php (or vise versa)

The local server can handle upper and lower case differences, but not the online server.
Changing the file name back to it’s original name fixed the problem.
