The letters in the Knitting Dream code are all converted into numbers.

The usual landing of the dream Backstage Verification code is composed of numbers and letters, and sometimes the letters often do not see clearly, small part of me in order to facilitate landing, so the verification code all changed to digital.

The steps are as follows:

Open the include/vdimgck.php look around the 87th line, delete a section of the following code:

$chars = ' abcdefghigklmnopqrstuvwxwyABCDEFGHIGKLMNOPQRSTUVWXWY0123456789 ';

Delete all letters reserved numbers after deletion as follows:

$chars = ' 0123456789 ';

If the captcha only wants letters, just remove the 87 lines of code and keep the letters.
