Problem with translate
It seems you've not read the support topic I directed you. If you use POT files you should change the WordPress language to allow wpForo load the new language. I see your WordPress is in English yet. You can change it in Dashboard > Settings > General admin page.
P.S: Please ask questions using text sentences, it's hard to understand your questions with image+1-2 words.
Please send admin login details to support[at]gvectors.com email address. We'll login and try to fix your issue within 1-2 days.
You're WordPress Spanish and wpForo Spanish translations don't match. The WP is Spanish but wpForo only has Spanish Mexican.
