Hi Stefan,
Thanks for your suggestion. Tried to upload the zipfile from the admin plugins page, but got another error similar message:
Installing Plugin from uploaded file: slideshow-jquery-image-gallery.zip
Unpacking the package…
Could not copy file. C:/Users/Admin1/…/Instant WordPress/InstantWP_4.3/iwpserver/htdocs/wordpress/wp-content/upgrade/slideshow-jquery-image-gallery/slideshow-jquery-image-gallery/style/SlideshowPluginGeneralSettings/general-settings.css
It is a bit annoying, but I’ll try your plugin another time on my live website. Maybe I’ll do a re-installation of Instant WP altogether, but not for now. Will wait for the lightbox option to be released before I do. Thanks again!
Anyone else by any chance familiar with this “Could not copy file”?error message?
