I am also having same issue. I tried Automatic update from 4.4.2 to 4.5.1… It said update was successful but still saying it’s on 4.4.2 and showing upgrade message. I tried manual update too. But result is same. Can anybody help in this?
Even I have same problem(warnings all over CP). Moreover after update my theme “Arras” got black background instead of its earlier marbel white bg… I have manually reverted the plugin to 3.7.. Now everything works fine…
Request for the developer to fix this. Thanks
