I've got an interesting bug(?).
If I try to insert certain URLs (they don't have to be wrapped in an anchor tag) into an article Joomla prohibits saving this article until I removed the URL.
e.g. given the following article content:
Code: Select all
<p>
https://google.com<br>
https://maps.app.goo-gl/xReGmqGrPCJHGkSj6<br>
https://goo-gl/maps/iXNaXb44kwPd89zt6<br>
https://bit-ly/s213rf
</p>
With only the google.com link I can save the article. As soon as I insert the (shortened) google maps or bit-ly URLs the POST request that tries to save the article answers with a 200 status code and the browser downloads an index.php with the following content, article is not saved.
Code: Select all
<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">
<html><head>
<title>503 Service Unavailable</title>
</head><body>
<h1>Service Unavailable</h1>
<p>The server is temporarily unable to service your
request due to maintenance downtime or capacity
problems. Please try again later.</p>
</body></html>
I've tried this at different times of day (if the site should really be overburdened), tried with TinyMCE and without any WYSIWYG editor. Disabled all content filtering for my user group (global configuration -> text filters -> no filtering). I instructed TinyMCE to use Joomla Text filtering (plugins -> TinyMCE -> Use Joomla Text Filter).
I told joomla to log anything (all levels, even deprecated APIs and so on) but there is just nothing of interest in the logs.
Currently I'm lost and have no clue what to do.
To me it seems that Joomla has some kind of (wrong configured) spam/URL shortener protection when saving an article. I've discovered the same problem with [youtube] share URLs (e.g. https://youtu.be/qyYmS_iBcy4). Any ideas what I can do/check?
This seems to be a long standing problem... See viewtopic.php?t=973967
