hi there,
I just tried this out and get the same issues.
Some variables are undefined, namely addslide, removeslide.
Defining these variables with NULL value at the start may resolve these errors.
Notice: Undefined index: removeslide in /media/DriveD/sdb1/www/www.faribasoltani.dev/wp-content/plugins/slider-image/sliders.php on line 192
Notice: wpdb::prepare was called incorrectly. The query argument of wpdb::prepare() must have a placeholder. Please see Debugging in WordPress for more information. (This message was added in version 3.9.) in /media/DriveD/sdb1/www/www.faribasoltani.dev/wp-includes/functions.php on line 3245

A prepared statement requires parameters.
Also I cannot amend the basic slider options on the right hand side of the test slider. I cannot copy the code tags in the basic usage fields.
so until these items can be fixed I am going to have to return to this plug in at a later date.
thanks
Andi
