burt Posted June 20, 2017 Share Posted June 20, 2017 @ce7 you probably need to state which addon you are attempting to add. Almost all addons are defunct with the new versions of osC. Link to comment Share on other sites More sharing options...

It will be great to know what causing it and how to fix it. (how to read the warning message and find the solution...) Many thanks in advance.

Dan Cole Posted June 21, 2017 Share Posted June 21, 2017 @ce7 Lyn...you're testing this old guys memory. I seem to recall having similar problems with some old addons on a php update. Try adding.... ob_start(); to the beginning of the add-on you installed....just before application_top.php being called so it looks like this... ob_start(); require('includes/application_top.php'); It may or may not solve your problem. I think it is worth a shot...I believe it worked in my situation without any ill effects. Dan Need help? See this thread and provide the information requested. Is your version of osC up to date? You'll find the latest osC community version (CE Phoenix) here. Link to comment Share on other sites More sharing options...
