Anti-Spam Options - reCAPTCHA v2 Human Verification

(Note: This mod was renamed. The original name was "New reCAPTCHA Human Verification")

What is it?
----------------------------
This mod adds reCAPTCHA v2 as an option in the Human Verification Manager.

Note: The original reCAPTCHA used default keys if you didn't enter your own, so you could leave the key fields blank. This version requires you to have your own keys for your domain. To create them, go to this page (click on the "Get reCAPTCHA" button). It may take a short time after creating the keys before they will work, so if you get "ERROR: Invalid domain for site key", wait a while and try again.

vb3 version is here: https://vborg.vbsupport.ru/showthread.php?t=315964

Installation:
----------------------------
1) Upload the file in the "upload" folder to your server.

2) Import the product XML file from the Product Manager.

3) If you don't already have keys, go to this page and create keys for your domain. (If you already have keys you can get them from that page as well).

4) Go to Settings > Human Verification Manager, select "New reCAPTCHA" for the Verification Library, and click Save.

5) Enter your keys on the options page, and select the light or dark widget as desired (apparently white and black are the only options at this time). You could select "Audio" to default to audio instead of image for the challenge, but the widget seems to have a bug in it at the moment so I recommend leaving it set to "image". Click Save when you're done selecting options.

6) You can check the configuration and do a test by clicking on "Click here to test connection" which appears under the description in the Human Verification Manager.

7) Do a test registration (or other action that requires hv) to test that your keys are entered correctly and everything is working.

8) If you are upgrading from version 0.9, you can remove the file includes/class_humanverify_newrecaptcha.php (the one without the third underscore) from your server.

History:
----------------------------
1.0 (Feb 22, 2015)

• Cached template (required renaming the uploaded file from
  class_humanverify_newrecaptcha.php to class_humanverify_new_recaptcha.php)
• Removed default keys (which didn't work anyway)
• Removed trademark symbols
• Changed execution order of plugins from 5 to 4, to make sure this product
  works with another HV add-on that has a bug.
• If "New reCAPTCHA" is selected when this mod is uninstalled, the hv library
  is switched to 'disabled'.
• Added a test option to print out more information about verification failures

0.9 (Dec 11, 2014)

• Initial Release

its the same when using the already implemented, old recaptcha or the image-verifikation, which says that the letters are not typed in correctly. does someone have an idea how to solve this?

We really need an answer as to why, when others, who have posted in this thread, say they don't have this issue.

The recaptcha server-side verification needs to connect to google to verify the response, so your php needs to have "allow_url_fopen" set to true, or else you need cURL in your configuration. I don't have a lot of knowledge about how hosting is usually set up, but I suppose there could also be network issues, i.e. maybe some hosts don't allow scripts to make network connections at all, or maybe they're limited to certain addresses.

Do you have "allow_url_fopen" set to on, or cURL in your configuration on the server? If you don't know go to ACP --> Maintenance --> View PHP Info and look there.

Which we do, and it is set 'On'. However, enabling reCAPTCHA results in the same "reCAPTCHA? could not be verified due to server issues. Please try again later."

allow_url_fopen is already ON
cURL is already enable

Does the old version of reCaptcha work for you?

[tanzeelniazi]

People who are having problems with this (and maybe also with the original reCaptcha), can you tell me what version of php and vbulletin you're running? I'm thinking of making a new release of this mod that has a debugging option, but first I thought I'd see if the problems might be related to recent changes in vbulletin code.
