Hi, there could be a temporary problem with the installer. If you are unable to update automatically, please go to https://toolset.com/account/downloads and download a fresh copy of Types 3.3. Deactivate and delete Types from your site, then install the new version you downloaded. Your custom post types and fields will remain in the database, so you won't lose data.
Hi, the download isn't a zip file. I can upload only zip file into plug in area.
Which file should I upload? Why don't you provide an easier way to manage your product?
Clicking on the download link should provide a zip file. Could you let me know what kind of file is being downloaded? From this we can see how best I can provide you with the zip file.
It seems what is happening is that you are extracting the files from the zip. Try checking your downloads folder to see if you see a file called types.3.3.zip
