Fatal error: Call to undefined function exif_imagetype() in xxx-path\wp-content\plugins\content-progress\content-progress.php on line 481
Using WP 3.5.1
I like your plugin but I am getting the above fatal error under the "Additional included icons' Information in admin.
I looked up the error and I am seeing a lot of issues with using exif_imagetype overall. The suggestion I have seen is to use "getimagesize" instead as it does return the TYPE very good according to what I read.
Just a suggestion. Since EXIF extension has to be installed in php.ini for it to word and some servers don't.
However, I also see that there is no function defined for exif_imagetype in your file.
For me, I just changed the exif_imagetype with getimagesize and the rest of the page shows up now, the get support section. I hope that corrected the issue and didn't just hide it..
