It seems there was data corruption issue most likely from migrating db that created duplicated rows in dashboards table, dupes removed and its working fine again.

Is this similar to https://support.zabbix.com/browse/ZBX-26691 (Dashboards blank after upgrade from 7.2.10 -> 7.4.0) , if so, watch that for input or updates.

Hi it seems different, I'm having php errors before anything is rendered at all while the linked is about JavaScript issues.
