PROBLEM TO UNLOAD THE MUSE THEME
Good morning, I have managed to move my website created in Adobe Muse to WordPress through the MWUSE plugin up there, all good, the problem I have now is that I cannot edit it to change content from WordPress and the MWUSE Thema does not appear because I It gives an error when uploading the zip file, the message that appears to me THE PACKAGE COULD NOT BE UNCOVERED, THE STYLE CSS SHEET DOES NOT HAVE A VALID HEADER FOR THE THEME.
Does anyone know why I am getting this error? I also do not know if the MWUSE Thema needs to appear in the Thema section or if I can modify it only from the Edit Page section. Thank you very much in advance
Can someone please help me?
