here is what I have in General Settings:
Compatibility Mode
This option enables some compatibility features in order to work seamlessly with other plugins. If you are experiencing conflict problems, you might want to disable this option switching it to no.
Log Errors On Screen
This option enables the SRP error logging system. Switch this to yes if you want to log potential errors or warnings on screen.
No-Posts Image Placeholder
This is the default image that appears when no other images are available inside a post. You can use the one you prefer by simply typing in the full URL of the image. If you leave this field empty, the default no-image placeholder will be loaded instead.
Default size: 200px x 200px.
JPEG Image Quality Ratio
This options sets the JPEG quaility ratio when the ‘Custom Thumbnails Option’ is enabled. Numerical values are accepted only. 100 is the maximum quality, but 80 is an acceptable compromise between file size and image quality. Range: 0 to 100.
Disable Plugin CSS
This option enables/disables the built-in widget stylesheet. Set this option to ‘yes’ if you wish to use your own CSS.
