I am using wysiwyg web builder 11.6.5 and after a hard drive crash I was forced to reinstall my system, including WYSIWYG. After installing the software, manually install the extensions, which previously had backed up, but despite the window said that the extension had been successfully installed, these did not appear in the list of my s. This happened with the extensions, which no longer appear in the official list, as an example: data viewer and onlyne photo gallery.Obviously, I can not open the projects that contain these extensions.Already downloads the extensions again but still does not install them.What I can do???
