Thank you Andoverit!!!
I deleted the Portfolio Slideshow folder, then uploaded and activated the older 1.5.1 version. The slideshows on my website are now working again!
For those of you that are as ignorant as I am about working with this stuff, this is what I did in more detail. My website is hosted on HostGator, so I’m not sure how that would make things differ…
(1) I started by downloading the old v1.5.1 zip file for Portfolio Slideshow. It’s found here:
https://ww.wp.xz.cn/plugins/portfolio-slideshow/developers/
The downloaded file will be used later in step #7
(2) I logged into cPanel. (www.footballweblog.com/cpanel for me.) This brought me to HostGator’s Control Panel. I scrolled down to their File Manager tool in the Files section and double-clicked the icon.
(3) I was prompted to select a directory to open. I didn’t have a clue, so I went with the default which was “Web Root (public_html/www)”. This apparently took me to the files on the HostGator server.
(4) Next I went into the wp-content folder by double-clicking it. Next I went into the plugins folder. Lastly, I found the portfolio-slideshow folder and deleted it. Doing this apparently removed the entire Portfolio Slideshow installation that refused to work correctly. Once this was done, I closed the cPanel File Manager and logged out of HostGator’s Control Panel. Everything else is done through your WordPress’s wp-admin screen for your website.
(5) Go to your wp-admin screen. (www.footballweblog.com/wp-admin for me.)
(6) Select Plugins > Add New. Select ‘Upload Plugin’ from the top of the screen.
(7) Browse to the .zip file you downloaded earlier, then hit the ‘Install Now’ button.
That’s it! You should now be running the old v1.5.1 version of Portfolio Slideshow that works!
Hope this helps someone — and thank you so much once again to andoverit!!!
Kind regards,
