Hi Ernest – thanks for quick reply. I did what you requested and reinstalled the update again. It worked perfectly this time – and site search also working fine. Thanks – that solved the issue. I normally leave plugin as is – and then install over existing plugin. I haven’t used the WP plugin manager and don’t use FTP – and it seems to automatically replace the existing with latest version. Do you recommend that I delete existing version first, before loading new installations? I am a little bit confused now? But thanks – I am glad you could help resolve this error issue for me.
