Getting error of entitymapper.php 99 and module.php 318

[cematesh]

Deprecated: array_key_exists(): Using array_key_exists() on objects is deprecated. Use isset() or property_exists() instead in /home/hosting/webapps/outleto/src/Adapter/EntityMapper.php on line 99

and 

Unknown error on line 318 in file /home/hosting/webapps/outleto/classes/module/Module.php
[8192] array_key_exists(): Using array_key_exists() on objects is deprecated. Use isset() or property_exists() instead

After getting the debug mode, I cannot reach to performance page.

I have noticed the problem when trying to translate some words on localization. The buttons were not clickable and the options were readable. So wanted to change to debug mode to see what's going on and the error is below..

 

PS. I am trying to upgrade my theme from 1.6 to 1.7 if it does help 😕

 

Any solution for that? 

 

Thanks in advance!

Did you manage to find a solution? I just started out with PrestaShop and I'm getting the same error message when I try to switch to debug mode

[Kristophersson]

For me changing PHP Versions worked. Check this page to see which php version should be used with which prest shop version: https://devdocs.prestashop.com/1.7/basics/installation/system-requirements/

I think you need to change your php version to 7.2

Worked for me too, many thanks !

My pages loading time had gone from 2-3 secs to 40-50 secs, it is back to normal now.

@Nicolas R

Did you enable cache and combine js and css. When this value is set load time will decrease.

Thank you

So, how can we fixed this?
change the php version is not the right solution.

I'm also asking how can we fix this? Have a white page and this error: 

Runtime Exception. failed to start the session because headers have already been sent by...at line 99

Change php to 7.2 is not an option as the provider does not support less than 7.4 :((( and will soon go to 8.0

Website in online but to backend...getting a white page.

Any idea what I can do?

Thx!!!!

Hello again.

Is there any chance to fix this problem without going back to php 7.2 ?

My provider does not support php 7.2 anymore, only 7.4 and it was working fine on 7.4 before.

I think when I wanted to upgrade a module it happened, maybe the model wasn't well maintained...? I deleted it with file manager but still get no access to the backend.

Please is there anybody with an idea because we soon facing php 8.0 and I'm sure some will get into trouble with presta...

Appreciate any input regarding this issue...!!!! Thx
