My settings: Joomla 4.2.0, PHP 8.0.17, MariaDB: 10.3.32

I have the issue that I get a blank screen only (even with maximum error reporting) when I tried to open a condition. It makes no matter to try this from the component or inside a module.

So I delete the Advanced Module Manager but the RL Conditions component still keep (??). I delete it with the Joomla Extension Manager. Then I reinstalled Advanced Module Manager.

I can make new conditions but when I try to access them in the component list ... blank screens only. Making a new one there is possible but the web page has to be refreshed to see it. "Save and New" reports this error: "No direct call to page allowed"

In other word: I can make new conditions and delete them. I cannot open or change any conditions.

Unfortunately I cannot give you an error log, because I get no one, even with maximum error logging.

Not possible - installation is in an internal network. Remote access is not allowed. But I can try to reproduce this error on a test installation which can be reached form outside. But this takes a bit of time because I am very busy in the moment. You will get an information when it is ready. Thanks 🙂

Enjoy your holiday. 🙂 Issue is fixed - nothing wrong with your extension.

My fix:

Today I make a copy of my Joomla installation and got an error message the first time:

Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 507904 bytes) in /libraries/regularlabs/src/StringHelper.php on line 234

Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 253952 bytes) in /libraries/vendor/symfony/error-handler/ErrorRenderer/HtmlErrorRenderer.php on line 273

Memory size? -> so I checked my memory_limit in php.ini 8.0.17 and compare it with my php.ini 8.1.1 (where I have no issues) - eh voilà - increasing the memory limit fix my problem.

Sorry for this unnecessary effort, but I received an error message for the first time today (on the text server). The live system only gave a white screen, which is not really helpful.

Again my thanks for the quick feedback.
