Hi @mariosgr,
I just checked and found only these three addons licenses are active for you wpforo-topic-prefix, wpforo-emoticons, wpforo-cross-posting. Make sure they are activated with the new license keys you've purchased a few months ago. Other addons licenses are expired.
Check all, by clicking the [Check update] button in Dashboard > Updates admin page. If the License Activation alerts are still there, then their license keys are expired. You can continue to use them as long as they compatible with the WordPress and wpForo new versions without the license activation. Or you can renew them with 30% discount as a returning customer.
i place the key for examle to cross blog and is not keeping it.
