Please advice, appreciate any help

We are on OJS 3.4.0.4

error inside Console:

Hi @Omid,

Have you checked your PHP error log? That tends to provide more clues than the console error log does in these instances.

Thanks for your reply.
We don’t see any error inside the error log of the system.
However, we see these warnings:
