Web host played with APC, now FluxBB is broken

Having problems with my site, and it's inconsistent behaviour. I'm getting the following errors, sometimes consistently, sometimes randomly:

error_log (throws 500 in browser):

PHP Warning:  PHP Startup: apc.shm_segments setting ignored in MMAP mode in Unknown on line 0

partial responses in browser when viewing topic, followed by error message (nothing logged in error_log):

Fatal error: Cannot run code from this file in conjunction with non encoded files in /home/silverst/public_html/forums/lang/English/pms.php on line 7

The first appears to be related to APC segment size, and the second a clash between APC and Zend. Here's the APC details from phpinfo():

apc

apc.user_ttl    0    0

Anyone got any suggestions? The web host conducted server maintenance last night, and only a very few customers are experiencing problems like this, so I'm not sure how I'm going to go getting them to make system-wide changes to resolve these issues. Are there any local overrides in a local php.ini or similar I could make to alter the APC settings?

This is related to a mod ("Private messages" ?).
That's all i can say.

Re: Web host played with APC, now FluxBB is broken

What I don't understand is why - pms.php is just a language file, here's the contents, line 7 highlighted:

<?php

);

It's just a regular array of strings - the error related to pms.php was actually triggered when viewing a topic - sometimes the topic shows, other times I get this error. The mod has been installed for months - no software changes have been done for weeks - but the web host performed "system upgrades" about 10 hours ago that caused this behaviour to occur.

Re: Web host played with APC, now FluxBB is broken

No idea about overrides but I would get on to your host to fix it, APC is known to clash with Zend optimizer so why they think it's smart to run both I've no idea. If they don't fix it I would suggest looking for a new host, I sure as hell wouldn't want to be hosted by some monkeys that think it's okay to install programs which are known to clash and then refuse to fix it.
