Hi @Aida_Quliyeva,

Which of our applications are you using, and what version? Have you checked the file permissions in your cache directory (and all of its contents and subdirectories)?

there is no applications version is 2.3.6. I am compressed all files and
sql and download. then i delete all files and sql (restart everything).
After i upload all files and sql. But I have white page.

Hello Aida,

if you use a OJS 2.3.6 the best advise is to upgrade your OJS to 2.4.8-1.

Hi @Aida_Quliyeva,

Did you perform the database upgrade step of the upgrade process? See docs/UPGRADE for instructions.
