I am developing in the MAMP/MAMP Pro (PHP 5.3) environment using the Rocket Theme Crystalline template. The site also has active SOBI2 and K2 installed. This had been working fine for the past many months. Recently, I decided to use the Syndicate template and did a standalone install. I also upgraded Gantry (now 3.1.6) and installed the most recent RokNavMenu a couple of days ago (forgot the version).

When I tried to load with Syndicate I have a blank screen.

Here is the contents of the php_error log:

The version I believe I have is 1.2.1.

I searched my system for files with the name jwsig.php and noticed the following:

mamp/htdocs/irc/plugins/content/jwsig.php

mamp/htdocs/irc/plugins/content/jw_sig.php

I've also attached a screen shot with error message displayed on a page.

Can anyone provide some insight into this?  I appreciate any assistance.

These are not errors but notices...
Use .jpg instead of .jpeg images.

Katia, thanks for your comment.  I do not use the .jpeg extension.  All such images in this format use the .jpg extension.  The site had been working fine before, so I do not believe this relates to the file extension.
