Hi,

I am getting the following error in my apache error log:

mod_fcgid: stderr: PHP Warning - preg_match_all(): Compilation failed: invalid range in character class at offset 7 - file: /forum-plugins/mentions/library/sp-mentions-components.php - line: 18 - function: preg_match_all.

Line 18 in bold below:

function sp_mentions_find_mentions($content) {
preg_match_all('/\B@([\w-\.]+)\b/', $content, $matches);
if ($matches) {
$names = $matches[1];
} else {
$names = array();
}

return $names;
}

This is due to php 7.3

I had this problem in different areas of my site.

I solved this with your plugin by changing line 18 as follows (there is 1 tiny change hard to spot: an extra /)

preg_match_all('/\B@([\w\-\.]+)\b/', $content, $matches);

Hi:

Thanks - we'll take a look at it and push an update if necessary.

One thing to look for is to see if the change causes a "compilation failed: invalid range" message.  

Thanks.

Hi,

Has my fix been integrated in the plugin? The fix solves the errors in the logs and does not create additional errors.

thanks

Hi:

Version 3.1.1 should have resolved this issue. If you install the premium installer (available from your account downloads if you don't already have it), it should give you the latest version automatically.

Thanks.
