HI, I read in another forum post that one must re-zip the file as macs seem to automatically unzip them. I did that before attempting to upload into plugins but keep getting an error message:
“unable to create directory uploads/2015/07. Is its parent directory writable by the server?”
From the error message you’re getting it sounds like you might be trying to upload Microthemer via the media manager. WordPress actually has a dedicated page for uploading the plugin via the plugins section of the WordPress admin area.
Please let me know if you’re able to find the plugin area of WordPress and install Microthemer. If you’re still struggling you can send me login details for your site via the following secure contact form and I will install it for you:
