Hi @premolar,

From the log it is clear: you ran out of memory. Either there is not enough memory or your memory setting is too low.

Regards, Primož

I have increased memory_limit 512M and it has been solved.

Thank you so much.

Hello @premolar
please can you inform me where you increased memory limit, on the server, or in OJS, please inform me.
Thank you
Lukas
