Hello
usually that's an error caused by the display of an error : so are you sure there is no other msg displayed too? Display the source code (Ctr+U usually)

My changes limit the size of album/category images to a max of thumbnail for guests, in addition to limiting the size of individually viewed pictures as did the original plugin.   That part would be suitable to merge into the plugin. 

In addition, I allow guests to view full size images of albums with permisions for a group named 'visitor_public'.  Probably that part is not suitable for merge in.  In fact probably I would have been better off using the "who can see this" access mechanism for Evenerybody/Frieds/Family etc. but I didn't understand it when I started.

Btw - I am a bad, greedy and selfish person.  I like using free and open software, but contributing?  It hurts not to be paid!

Well you have to disable one by one the plugins to see where the problem is

With all plugins disabled, except Contact Form and Social Buttons, the warning message still appears.  The only two differences I can see are:

1. that on this site (with the error) the twitter button has a "1" next to it, because I had successfully tested sending a tweet some time ago.  On the other site, the twitter button has "0" next to it.   I just tried sending a tweet from that site, but it does not seems to register and a "0" still appears next to the twitter button.

2. on the site with the error, within the Contat Form admin page tab <Email> I had added two categories for two separate email addresses ("Tech" and "Art").  I deleted them (and the categories) so at least in the UI it appears as in the working site, and retested, but the warning message still apprears.
