ExhibitPage.php errors

Hello all,

I am an Omeka beginner. I have an Omeka installation and have added a number of plugins, including Exhibits.

I am finding I am having some issues with the Exhibits plugin however. I am able to begin the set up of an exhibit, including initial selection of page style as well as being able to add content. However, whenever I attempt to "Edit Page" layout, or Save Changes I am met with this error.

Notice: Undefined offset: 1 in /var/www/html/omekatest/plugins/ExhibitBuilder/models/ExhibitPage.php on line 78

I've taken a look at line 78 of ExhibitPage.php and I'm not seeing anything out of the ordinary. Does the Exhibits plugin have compatability issues with other plugins? I have edited some of the php related to the appearance of our Omeka site (customized some of the css as well), could this have broken the Exhibits plugin?

I'm currently at a loss as to what could be throwing this error and I have not seen this issue coming up anywhere else. Any thoughts?

Uninstalling the Exhibits plugin, then reinstalling it seemed to fix the issue. Strange!
