I had PDF Stamper working fine with eStore and eMember last weekend but yesterday the client who bought the plugin package tried to make a color formatting change to 93 93 255 (blue) to the stamped PDF, and the downloaded files seemed to now have no stamp.
I selected the area in the download where the stamp should be, and discovered that it was there but it was transparent/invisible.
I tried to change it to 0, 0, 0 (black) for testing but it would only change to 93 93 0, which is yellow - and it now prints fine but it is in light yellow.
I tried many times to change it but it's stuck on the yellow 93 93 0, so I took screenshots of all the settings and deactivated, deleted and re-uploaded and reactivated the plugin.
But it still won't let me change the color and it stays yellow.
Not sure what to try next. All seems to be working but we can't change the color of the stamped text.
Using the latest version of the plugins and WordPress and no other plugins activated.
I can't provide a link because it can't be seen on the front end because it's part of the membership area.
