Regarding your browser console errors you can follow this procedure.
SELECT * FROM user_filter WHERE criterias LIKE '%"status_severity_code",null%';
This SQL request will give you all the filters that has the malformated criterias saved in the database.
You can update the column criterias in the DB of the filters that match the LIKE condition and the problem will be solved.
To update it, you can copy/paste the “criterias” value and replace ["status_severity_code",null] by ["status_severity_code","asc"]
Here is an example:
UPDATE user_filter SET criterias ='[{"name":"resource_types","type":"multi_select","value":[{"id":"host","name":"Host"}]},{"name":"states","type":"multi_select","value":[{"id":"unhandled_problems","name":"Unhandled"},{"id":"acknowledged","name":"Acknowledged"},{"id":"in_downtime","name":"In downtime"}]},{"name":"statuses","type":"multi_select","value":[]},{"name":"host_groups","type":"multi_select","value":[],"object_type":"host_groups"},{"name":"service_groups","type":"multi_select","value":[],"object_type":"service_groups"},{"name":"search","type":"text","value":""},{"name":"sort","type":"array","value":["status_severity_code","asc"]}]' WHERE id='2';
