I also tried downgrading to the previous version of Alkivia that I had, and the error was still there. It also shows up on top of the page when I’m browsing around the WP dashboard.
I just realized I cut part of the error off. Sorry.
Warning: Cannot modify header information – headers already sent by (output started at /home/username/public_html/wp-content/plugins/alkivia/components/gallery/class.gallery.php:1) in /home/username/public_html/wp-content/plugins/sidebar-login/sidebar-login.php on line 311
When I use Alkivia with the Sidebar Login plugin off, it works fine except the error appears again when I edit a theme template file for example (Warning: Cannot modify header information – headers already sent by (output started at /home/username/public_html/wp-content/plugins/alkivia/components/gallery/class.gallery.php:1) in /home/username/public_html/wp-admin/theme-editor.php on line 69), and also when I active/deactive any plugin (Warning: Cannot modify header information – headers already sent by (output started at /home/username/public_html/wp-content/plugins/alkivia/components/gallery/class.gallery.php:1) in /home/username/public_html/wp-includes/pluggable.php on line 865). Right now I had to deactivate AOC in order to get the error to disappear.
I hope this can be fixed soon. Thanks in advance.
Looks like when editing a template file, you introduced a blank space after the closing or before the opening PHP tags. <?php ?>
I would recommend to never use the closing tag at the end of file, as it is not required and avoiding it would prevent some problems. Some editors introduce a line break at the end of the file witch causes this.
Oh ok. I re-installed it and carefully edited the templates and it’s working fine now. Thank you!
