Unexpected error: Now Publisher not working properly

Error Code:
Unexpected error: Allowed memory size of 536870912 bytes exhausted (tried to allocate 4096 bytes) in PdoExtended.php on line 161 category:6

I’m using hostinger.com for the hosting.
PHP 7.4

So it was working great until this error happened when I was using Publisher section in Backlight 4.1.

I can’t delete albums in album sets or add images. image faults to upload too.

What can I do to fix this? Can backup the design I have already created before reinstalling Backlight from the beginning?

Hi @haydengo, I’ve seen this happen with one scenario of an album or album set not being linked to its parent. Can you please provide me with a Backlight admin login, by clicking on my profile name and sending me a message? I’ll then check the database to see if that’s the case.

Edit: for reference, this is the case that came up previously Memory error when trying to create a gallery for a Theater album
