    Captcha not showing characters

    Asked by omegatx on September 02, 2016 at 11:29 AM

    I used a form I had created last year. The following towo issues occured

    1. The upload file would not accept pdfs.

    2. The captcha would never show the characters. The window showed a constant revolving circle.

    So I designed a new form. Now I have the same problem with the captcha showing the revolving circle.

    What is going on?


    What am I doing wrong?

    I just tried your form, and the captch worked fine. On regards of the upload field, I tried uploading a PDF file, the error given was related to the file size:

    So, you may change the file size, and make sure the PDF file type is allowed, please check these guides:
