Hi, community, I experienced the same problem yesterday, I fixed by running the command from @sravanthi17 from this link
sudo rm -rf /opt/openmrs/lucene/indexes/* sudo service openmrs restart
but today I still have the same problem and I tried the following command sudo service openmrs stop sudo rm -rf *.openmrs-lib-cache sudo service openmrs start
Any suggestions for a permanent solution, please.
