Dear All, I have recently migrated the data from very old 1.2.1 to 4.2 on Ubuntu 14.04 and postgresql 9.3, every thing is working fine on jspui interface but except Browse feature Discover is not working on xmlui interface, whenever i enter a search term or just click on advance search it gives following errors. I have tried on ubuntu 12.04, postgresql 9.1 but facing data migration problem se opted 14.04 where it works fine.
Please suggest?
