Template crashed

Hi guys, thanks for your wonderful work! I just bougt EasySocial Professional and I am developing the page since a few days. Today I tried to turn off the toolbar in Templates/Toolbar/Show Toolbar. This crashed the template and included the following code in the back-end AND front-end (this happened in Frosty and Wireframe template). Can you please help me to fix it?
Here is the text that shows up in back-end and front-end:

Warning: is_file(): File name is longer than the maximum allowed path length on this platform (1024): {"stream_icon":"1","stream_datestyle":"elapsed","stream_dateformat_format":"Y-m-d H:i","dashboard_login_guests":"1","dashboard_feeds_everyone":"1","dashboard_feeds_friendlists":"1","dashboard_feeds_groups":"1","53a9c685958fa":"1","dashboard_groups_total":"0","dashboard_feeds_apps":"1","dashboard_mini_registration":"1","registration_profile_headers":"1","registration_profile_avatar":"1","registration_profile_desc":"1","registration_profile_type":"1","registration_profile_users":"1","registration_progress":"1","registration_profile_selected":"1","toolbar":& in /usr/local/sites/gapalumni19HAw/public_html/administrator/components/com_easysocial/includes/foundry.php on line 1040

Thank you very much! Greets from Vienna, Austria
