Hi there!
I’m using WP 3.8.1 with multisite and Image Watermark 1.2.1, on PHP 5.3.
I get notices on both front and back end:
everywhere front-end:
Notice: Undefined index: forlogged in C:\---\image-watermark.php on line 387
on watermark back end option page:
Notice: Undefined index: forlogged in C:\---\image-watermark\image-watermark.php on line 920
I tried ticking the option “Enable image protection for logged-in users also” but this option does not get saved so stayed unticked and the notices remain.
As a quick fix i set up every other option, saved Watermark options and edited the database manually:
-table: wp_options
-option_name: df_image_protection
added to the array: s:9:”forlogged”;
Note that if you save the options from WP back end afterwards it will erase the ‘forlogged’ key.
