@thom4s, If your localhost is working fine and the staging server is working fine, my first guess would be that the issue is related to the server and not Grav.
When opening /system/src/Grav/Common/Cache.php in VSCode I get the following warning on line 260
$driver = new DoctrineCache\ApcuCache();
@deprecated Deprecated
without replacement in doctrine/cache 1.11. This class will be dropped in 2.0
Not sure if the above is causing the issue though.
Does a fresh default installation of Grav 1.7.34 also throw the same issue?
… i find my error… i deploy with git. But i put some cache folder in the gitignore… so the cache folder in the vendors were not deploy.
I’m a idiot but i learn from my error
