[Plugin: Advanced Events Registration] Update to new version fails

Hey Sam. It looks my plugin and another plugin are both trying to send session information and failing. It sounds like there might be some extra space or a return/line break in one of the files. Either in my plugin or one of the others you have installed. Try turning off all of your plugins. Then activating each one and testing it while AER is activated.

Hey Sam,

I commented out the session function in my plugin (on your server) and I also disabled the FolioPress WYSIWYG plugin you have installed. That was causing problems with the event editor. You can enable it if you need to but it will make the event editor unusable while it is activated.

Hey,

I’m having a similar problem. Whenever I try to update or save a post I get the following: “Warning: Cannot modify header information – headers already sent by (output started at /home1/graphbyt/public_html/muevete/wp-content/plugins/advanced-events-registration/includes/event_register_attendees.php:779) in /home1/graphbyt/public_html/muevete/wp-includes/classes.php on line 1586”

This started after installing the Advanced Events registration plugin.

Any idea how to fix this ???

Thanks!

Another plugin may be passing header/session information. Try deactivating each plugin one by one until you can find which one may be conflicting. That way we can get an idea of where the problems are coming from. That may also help in the future if you have an issue like this again.

A quick fix for this is to open the event_regis.php file and go to line #43 and comment out “add_action(‘init’, ‘event_regis_session_start’);”

Hope that helps. Let me know if you still have problems.

Hi Seth,

Thanks for the reply.

Well here’s the kicker, Advanced Events Registration is the ONLY plugin I have downloaded and installed on my wp installation. So I’m at a loss here.

Also, there’s no function “add_action(‘init’, ‘event_regis_session_start’);” call in the event_regis.php file (or in any of the plugin’s files according to my find tool). Line 43 of event_regis.php contains this comment: “Fixed the problems with the radio buttons not staying checked.”

I’m working with Version: 2.1.15 of the plugin.

Also, the error messages vary. Right now I’m getting this one when trying to update a page “Warning: Cannot modify header information – headers already sent by (output started at /home1/graphbyt/public_html/muevete/wp-content/plugins/advanced-events-registration/includes/event_register_attendees.php:779) in /home1/graphbyt/public_html/muevete/wp-includes/classes.php on line 1586”

The error messages appear in a red box underneath the WYSIWYG editor and they also appear in a blank page if and when I click “update”.

Any ideas??

Thanks again for your time.

@gtothab,

Is this working for you yet. I removed some space that was in the end of the event_register_attendees.php file (version 2.1.16) that may have been causing the headers already sent issues.

Can you please update us on this issue? I believe I updated you via email.

Thanks!

Seth
