Error after online migration

Hello,

After the online migration of my website (from local development), I have an issue with SG Security Plugin. In the WP admin dashboard, when I want to go SG Security menu, I have the following popup error : “ERROR The string did not match the expected pattern.”

I tried to search in the database in order to find old url to update but I did not find it. And I also tried to delete and reinstall the plugin but it did not work (database entries are not reinitialized I guess).

Thanks in advance for your help.
