Hey. Hey,
I have installed OJS on Apache 2.x, PHP 8.2, Maria 10.5. The installation was successful, but after logging into the administration I get a blank page. In the frontend there is also a blank page
Can you advise me how to solve this?
Hi @Tereza_Vanacka,
For errors such as this, it is best to check your PHP error log and report on errors found there. Usually messages in those logs provide more clues as to what the specific issue is.

Thanks for sharing. I will flag this for our team to have a look at when someone is available.

Hi @asmecher.
Thanks for your advice. I have checked my hosting config and indeed, this function is currently disabled. Unfortunately, they can’t enable that only for my account so I have to try my another hosting. Hope everything will be alright.
