I installed the WOW Slider app for Windows and created a slider file.
I have uploaded the .zip file as a plugin via FTP.
I activated the Plugin in WP.
The WOW Slider menu appears, but there are "No sliders found".
If I try to upload a second time, I get the "Wrong slider" message.
I can not upload a second time unless I deactivate and delete the Plugin.
Any help would be appreciated.
