We have a fix that we're testing right now. If you're interested in implementing it to see if it fixes the issues on your site, we'd love to hear your feedback. We're planning a release over the next week with quite a few fixes, and this is likely going to be one.
To make the change, please edit the /plugins/system/jfbcsystem/jfbcsystem.php file. Around line 313, you'll see the following block of code:
/*
* Code to strip any {JFBCxyz} tags from head. Caused issues on some users sites in 4.3.1
* Removing until more error-proof method found.
//Get the head
$content = JResponse::getBody();
$regex = '|<head(.*)?</head>|sui';
preg_match($regex, $content, $matches);
//Remove the tag if it's in the head
$newHead = preg_replace('|{'.$tag.'(.*?)}|ui', '', $matches[0]);
//Replace the head
$content = preg_replace('|<head(.*)?</head>|sui', $newHead, $content);
JResponse::setBody($content);
*/Replace that whole block with the following:
/*
* Code to strip any {JFBCxyz} tags from head. Caused issues on some user's sites in 4.3.1
* Removing until more error-proof method found.
*/
//Get the head
$content = JResponse::getBody();
$regex = '|<head(.*)?</head>|sui';
if (preg_match($regex, $content, $matches))
{
if (count($matches) == 2) // more than one head is a problem, don't do anything
{
//Remove the tag if it's in the head
$newHead = preg_replace('|{' . $tag . '(.*?)}|ui', '', $matches[0], -1, $count);
if ($count > 0)
{
//Replace the head
$content = preg_replace('|<head(.*)?</head>|sui', $newHead, $content, -1, $count);
if ($count == 1) // Only update the body if exactly one head was found and replaced
JResponse::setBody($content);
}
}
}Make sure you do not leave the */ from the bottom of original block, or you will run into issues.
Please let us know how that goes for you. Also, please make sure you test on many pages of your site, not just the one(s) that were having issues. The code can modify the whole output HTML and affect other pages in a bad way, so we just want to make sure we're not trading a fix for one issue just to break another.
Thanks,
Alex
