em-xxxx.php pages showing up in every wysiwyg widgets

Most likely it’s because the other plugin is using the_content incorrectly, i.e. outside the loop, as documented here it must be in the loop:

I’ve seen this happen before, in all cases it was due to this.

Marcus,
thank you very much for your reply. I found that tag in one of the 3 .php pages in the wysiwyg widgets plugin. I will head over and address the problem in its support forum.

Just one more hint I would like to add in case the error might be caused by something else: the problem started only AFTER i had updated the events manager plugin (the other i had updated a few days earlier with no error consequences).

The problem lies with Events Manager. I installed another wysiwyg plugin: Smart Blocks and I have the same problem.

still pretty sure it’s not us. both plugins may be doing the same thing…. it’s a common mistake

I looked at the first plugin since it’s more popular (wysiwyg-widgets) and I can confirm they’re doing exactly what I’m saying:

$post = get_post($id);
....
$content = apply_filters('the_content', $post->post_content);

it’s not being run in the loop, so when we hook into the_content we’re assuming the $post is still the one of the page, not the individual widget.

Marcus,
Thank you for your reply and for taking the time to look into the other plugin. Your reply makes sense. I am in no way familiar with php coding, but I can always try to figure this out hoping I will be lucky and strike gold. So far no reply from the other side.
Thanks again. Perfect service.
