Hello,
I just installed the forum on a new site. I had some issues with installation not completing – it would say “installation complete” but then it would prompt me to install again. I disabled all other plugins, and it did install.
WordPress 3.9.1
Simplepress 5.4.2
Now, I am setting it up and trying to create topics, but I received this error:
Warning: array_unshift() [function.array-unshift]: The first argument should be an array in /problem-with-post-edit-buttonome1/ce4t/public_html/courses/byod/wp-content/plugins/simple-press/sp-api/sp-api-class-post.php on line 457
Warning: Cannot modify header information – headers already sent by (output started at /problem-with-post-edit-buttonome1/ce4t/public_html/courses/byod/wp-content/plugins/simple-press/sp-api/sp-api-class-post.php:457) in /problem-with-post-edit-buttonome1/ce4t/public_html/courses/byod/wp-includes/pluggable.php on line 1121
On the forum page itself, this message is displayed before the first topic:
Warning: Invalid argument supplied for foreach() in /problem-with-post-edit-buttonome1/ce4t/public_html/courses/byod/wp-content/plugins/simple-press/forum/content/classes/sp-list-topic-class.php on line 416
I’d appreciate help in resolving this.
Thank you!
