well I'd say that just adding that table again should solve the problem (if it's empty, it will filled automatically with default values at first login).
i am using (Version 2.06+ Build 151018) i can't get the reason why its have this kind of error because it was working fine for the last two days then when i tried to open the survey on the next day it shows me this kind of error.
i run mysqlcheck over the table, and it says ok plus when i execute show tables over the db it shows the list of the tables properly and also select * from lime_settings_global it displays the content. And also i have two limeservay databases and i tried to connect on both dbs by changing the dbname from application/config/config.php and same error is shown. I have another system on my server using mysql and all are working fine.
So do u think the problem is with the db?
