Fix fatal error when accessing the WP Edit Post interface and when BP Docs is active

[r-a-y]

Hi @boonebgorges,

I'm on a bug spree it seems. Came across another one:

PHP Fatal error:  Call to undefined function bp_docs_is_doc_edit() in \wp-content\themes\openlab-theme\lib\plugin-mods\docs-funcs.php on line 13

This occurs if BuddyPress Docs is active and when editing any post in the WP admin dashboard. When I looked at the docs-funcs.php file, it appears all the mods there are only applicable to the frontend. So this PR only loads up docs-funcs.php if we're not in the admin area.

I haven't actually tested if this breaks things for BP Docs integration yet, but I think it shouldn't.

Hi @r-a-y - This sounds like a serious problem that would need a very quick 1.1.1 of commons-in-a-box.

But I can't seem to reproduce it. The function bp_docs_is_doc_edit() is always loaded as long as BuddyPress Docs is active, whether in the Dashboard or not.

Can you give a full stack trace of the fatal error? I assume it's in the function openlab_disable_wplink_for_docs()? Could it be that this is a load-order problem? Is tiny_mce_plugins being fired very early for some reason?

I don't have a particular problem loading these functions only on the front end, as you've suggested, but I would like to understand the issue first.
