Plugin stopped working – only thing i can do is reset all settings

Hello,

When i wanted to change plugin settings i noticed that if i “check” box or paste new code into field and hit “save” button plugin just delete all changes that have been made. So for example if i paste adsense code and hit save button there is empty field . I cant do any changes in plugin not even set remote debugging .

Only thing i was able to do was reset all settings but it didnt help.

I also did these things:

– Deactivated all plugins
– Deleted plugin and installed plugin again
– Deleted cache

Website is : https://zvratenyHumor.sk we use plugin to show extra blocks in longer posts after paragraphs for other placements we put code directly.

This is probably because of plugin update or something because it was working fine for a long time for us.
