Hi to all,

i have a dnn portal (4.9.x if i can recall correctly) for about 1 year. I had enabled captcha login for administrator (only) login. The last 3-4 days, i had complaints that my client could not connect via login module, due to the fact that the captcha icon was broken. I checked it and it was true. The captcha image is not broken and as a result, i cannot enter the administration panel.

Could someone explein what has happened and the captcha stopped working correctly? Also, should i modify some database value in order to disable captcha and being able to login as the administrator again?

thanks in advance

Hi,

yes, i have tried in multiple browsers. In any case, the captcha login has been working for a long time till now.

Actually, it is a shared hosting environment. Do you suspect that some modification on the provider server could cause this issue? But what kind of modification?

I changed the module settings table and disabled the captcha. But i haven't figure out what has caused the malfunction.

I haven't changed the .net runtime, actually i haven't modified anything for the last 6 months. Also, the same issue appeared in another DNN portal installation (4.9.x also). In any case it is a shared hosting environment. Do you think they have changed something that affects captcha login?

thanks
