I want to customize some strings into moodle. so when i clicked on open
language pack for editing it will run completely but showing this error
"Error writing to database"
Please look at the Moodle Documentation in https://docs.moodle.org/31/en/Language_customisation#Database_error_seen_when_attempting_a_language_customization .
"... This error may be caused by a recent plugin that corrupted the database.
You are advised to check all plugins recently added to your site, and
test if removing a plugin prevents this error ..."
