Great!!!, i applied the Health Check plugin, and worked in the Troubleshooting mode, disabled all plugins and test them one by one.
At the end of the excersice, i identified the Orbit Comapanion plug in was the one causing the problem, so i disabled, and gallery started working again.
Actually the tool also allowed me to identify all the things i don’t really need and now i’m uninstalling them.
Thanks a lot for the recommendation!!!
Thanks, will give it a try and will let you know!!!
