I have updated my OJS from version 126.96.36.199 to version 188.8.131.52 and activate the version of recaptcha V2. When I go to the form in a magazine to create new users, I fill in the form and I click on the recaptcha button. When I send the form, I get an error and it tells me The characters you entered do not match the characters in the image. Check the characters and try again.
How can i solve this problem. Greetings.
