This error occurs due to the attempt to connect to a host to verify limesurvey updates . To be on the internal network , the verification fails , and tries to insert the error log with more than 1600 characters in the table settings_global , whose field stg_value has only 255 characters . This is a BUG of lime . As a workaround , change the column to text solves the problem . I hope this bug is fixed in a new release .
