Upgrade 1.10.3 to 1.11.10 fails at step 5

[EoinDubh]

I recently had to change ISPs and am having trouble getting one of my CMSMS sties back up. It goes tp step 5 of the upgrade and hangs at Building static route database...

The only error that I have seen so far is allow_url_fopen is off in php.ini. Unfortunately, I do not have access to make changes to php.ini on the server. Would this have anything to do with the hang? I am trying to get them to give me a local php.ini but so far, no luck.
EDIT - I just checked the server error log and see: PHP Fatal error: Cannot override final method CMSModule::can_cache_output() in path_t0_dir/modules/FrontEndUsers/FrontEndUsers.module.php on line 2021

Line 2021 is the final } in the file.

I recently did a pretty big upgrade of cmsms so Im hoping I can help

Can you confirm if you updated your modules before the cms itself?

try renaming FrontEndUser module directory before you upgrade. after upgrade, reverse to correct name and see what happens.
