 * Hello,
 * Thank you for creating such an awesome plugin. It is very useful and I am very
   happy it also enables me to share private Flickr photos; a functionality most
   Flickr plugins do not offer.
 * However, I recently ran into a bit of a problem. I had changed the version of
   PHP used for a website I’m working on from PHP5.6 to PHP7.0, and that is when
   I got into some unfortunate issues with the plugin. On PHP5.6, the plugin worked
   like a charm and displayed my pictures nicely, but on PHP7.0, I got an error.
   
   In the backend of the site, on the **Default Settings** page of the plugin, it
   showed the following error (in the box below _Your Photostream Preview_):
 * > Warning: Missing argument 1 for afg_error(), called in C:\domains\_my-website-
   > url_\wwwroot\wp-content\plugins\awesome-flickr-gallery-plugin\afg_admin_settings.
   > php on line 422 and defined in C:\domains\_my-website-url_\wwwroot\wp-content\
   > plugins\awesome-flickr-gallery-plugin\afg_libs.php on line 194
 * I had at an earlier date put the shortcode that linked to one of my created Flickr
   galleries in a post, which of course also showed an error where the gallery was
   supposed to be displayed:
 * > Awesome Flickr Gallery Error – error setting certificate verify locations: 
   > CAfile: /PHP7.0/cacert.pem CApath: none
 * I got the errors to disappear and my gallery to reappear, when I switched back
   to PHP5.6 (and cleared my cached galleries to be sure). However, this is of course
   not an ideal situation.
 * I hope there might be a solution to whatever is causing the problem?
