Fatal error when enabling caching

[zushiba]

I've got APC installed and can verify that it is operating properly. So I go to enable caching as it's currently disabled on my forum and I get the following error

Code Select Expand

Fatal error: Call to undefined function subsFunc2() in /home/user/public_html/forum/Sources/Subs.php on line 4363

If I press back and disable the caching it fixes this.

I do not believe that function is part of the standard SMF installation (It does not appear to exist in my clean copy of subs.php)



So... SMF version? Mods installed?

[zushiba]

possibly related to the subaccounts mod... (my first guess)

but you may have to do a search of each of the mods to find out which one added the call to subsFunc2

[zushiba]

It looks like Menu Editor Lite

Code Select Expand

//-- Labradoodle-360; Menu Editor Lite
if (empty($context['uninstalling']) || !empty($_REQUEST['package']) && $_REQUEST['package'] != 'Menu-Editor-Lite-1.0.5.zip')
subsFunc2($menu_buttons);
// End Labradoodle-360; Menu Editor Lite --//

yup, it does...

which then begs the question... did that mod get fully installed?

I suggest that you either uninstall the mod, or manually check each of the edits to confirm that it was fully installed.

[zushiba]

It's fully installed though there is one oddity.

Where it replaces in index.php

Code Select Expand


elseif (empty($_REQUEST['action'])

with

Code Select Expand


elseif (empty($_REQUEST['action']) && empty($_REQUEST['ajax_request'])

I have

Code Select Expand

elseif (empty($_REQUEST['action']) && empty($_REQUEST['ajax_request']) && empty($_REQUEST['ajax_request']))

[nend]

It can't be the if statement it has to be the function call, so even with that oddity it should still work, but it doesn't which means the function it is calling does not exist because there is code missing to add the function or include the file that contains the function. So in other words it is either a bug in the modification or the package didn't install correctly.

[zushiba]

Well so far as I can tell the modification itself is functioning correctly. It does all it's advertised to do.

[nend]

It may not be the code then, what are your settings for APC, maybe you have a bad byte cache or setting causing the problem.

[zushiba]

that seems to be working as well mind you I'm no expert.

[nend]

I don't know if it has to do with your 100% fragmentation level. I am no APC expert either, however in the time I have had it across all nodes I have never had that high fragmentation.

[zushiba]

Hmm, I increased it's available memory from 32megs to 64, I'll have to watch it and see how it goes.
