, referer=Unknown, servletErrorMessage=}Run the following SQL in the database to check the configured encoding:
1
select pe.*, ps.* from propertyentry pe, propertystring ps where property_key ilike '%encoding%' and pe.id = ps.id;In a typical scenario, the anticipated output would be as follows:
1 2 3id | entity_name | entity_id | property_key | propertytype | id | propertyvalue ---------+-----------------+-----------+-----------------------+--------------+---------+--------------- 100002 | jira.properties | 1 | webwork.i18n.encoding | 5 | 100002 | UTF-8=However, if you are facing the issue, the output of the above query would be:
1 2 3id | entity_name | entity_id | property_key | propertytype | id | propertyvalue ---------+-----------------+-----------+-----------------------+--------------+---------+--------------- 100002 | jira.properties | 1 | webwork.i18n.encoding | 5 | 100002 | desc
Cause
Due to a database refresh or update, an incorrect encoding was set for the property webwork.i18n.encoding, causing Jira to be unable to load the pages.
Solution
Run the following query to correct the encoding value:
1 2update propertystring set propertyvalue = 'UTF-8' where id = (select id from propertyentry where property_key = 'webwork.i18n.encoding')Restart the environment to ensure data integrity and reflect the updated encoding value
