Thank you. To be more precise, this error pops up when inserting. There is not an edit function that I am able to use with WA Captcha. Just so you know, I've always had an issue with every kind of captcha extension, not just WA.
After our Skype conversation, I replicated the e-cart errors, I'm including one that seems simple enough for you to understand, the other errors upon selecting/insert were thrown with empty line numbers / file name. I removed e-cart from DW CS6 for now, I'm just sharing the screenshot of the error and how it happened for your information.
The script you kindly gave was placed in the proper location, replacing the original which came within the captcha bundle (Super Suite). The error pops up after deleting the .DAT file as well as rebooting DW and Mac OS X Mavericks. I thought that replacing the file would work, I wonder why it didn't, perhaps Mavericks & DW CS6 related ?
Thank you for your continued support of an excellent extension Suite.
