Thank you both! Sorry for being so clueless about the product.

Hi - I'm trying to upgrade a 4.7.2 site running on PHP 7.4 to 4.7.4 on PHP 8.0. When I switch Apache over to use PHP 8 FPM, I get a white screen and an error like the below in the PHP error log file. [09-Nov-2022 21:15:10 UTC] PHP Fatal error: Array and string offset access syntax with curly braces is no longer supported in .../public/htdocs/applications/rules/sources/Secure/Application.php The contents of this file look obfuscated - with plenty of base64 encoded stuff (to make me think it's almost possible it's malware) ... but I guess it's more likely to be some way of embeddeding a license key in the product? If I comment out the single line in this file, I get an error like : Class IPS\rules\Secure\Application could not be loaded. Ensure it has been properly prefixed with an underscore and is in the correct namespace. EX256 I had a quick search of the forum for references to this magical file, or to the EX256 but nothing came up. I have a feeling I need a new license key? Or is something else up? Thanks in advance David. (Image shows the commented out version of the file that triggers the above error; blob obfuscated in the middle ... just in case)
