Feeling dumb here…have no /dev/urandom folder :S
/dev/urandom is from the file system root. You won’t see it if you are just looking at your home directory.
Another solution is to use php 7. The code that is failing is providing a function, random_bytes(), that is now provided by php 7.
Thank you @duncanc. But did I miss all of this info in release note? Was this there? I don’t think so…
@michelep You are correct, this information wasn’t in the release notes. I think that the developers did not realise the implications of using a new library.
Thank you @duncanc !!!
Installing mcrypt worked for me. Highly appreciate it!
Marking this as SOLVED
Where and how to install mcrypt? Feeling very dumb.
Exactly for about 3 years I couldn’t solve the error 500 when trying to access /admin, just installed new PHPList version 3.4.8
Used PHP List for more than 5 years before the error started to pop up. I’ve tried a lot of suggestions, none helped in my case
