papo2414 Posted June 28, 2021 Share Posted June 28, 2021 Hello everybody. With the latest update, 8.2, the option for my customers to access their Plesk panel from the customer area stopped working. When they click on that button, it opens the plesk login in a new tab, and before it was with automatic login. I already checked everything, even checked that the server was connecting correctly and the problem continues. Does anyone know how I can repair this? Thanks in advance for the help you can give me. 0 Quote Link to comment Share on other sites More sharing options...
websavers Posted June 29, 2021 Share Posted June 29, 2021 (edited) Same issue here. I just created a ticket with WHMCS support about it. I restored the modules/servers/plesk folder from my 8.1.3 backup and it works fine again with that -- I suggest doing that until WHMCS figures this out and releases a hotfix.

websavers Posted June 29, 2021 Share Posted June 29, 2021 Did their type error hotfix resolve this for you @papo2414? Support says it should, yet I had applied that hotfix before opening the ticket and it didn't do it for me. Just looking to see if you had the same experience. 0 Quote Link to comment Share on other sites More sharing options...

I have opened a ticket in whmcs however I have not received a response. I have not been able to repair this error. It seems to me that it was due to the last update. 0 Quote Link to comment Share on other sites More sharing options...

BUT in WHMCS defense there is a new site builder...... so that's a positive 😂 1 Quote Link to comment Share on other sites More sharing options...
websavers Posted July 2, 2021 Share Posted July 2, 2021 (edited) WHMCS staff said this on the topic: The Type Error hotfix must be applied With the 8.2 version of the Plesk module, they now send the server IP to authenticate with Plesk, which does not match the client IP and so Plesk invalidates the session To work around this, you must have the option in each of your Plesk server's enabled to not validate user IPs: 'On your Plesk server, please enable "Allow IP address changes during a single session" under Plesk > Tools & Settings > Active Plesk Sessions > Session Settings'. [The Plesk dev team told them this session setting was enabled by default, yet none of our servers had it enabled, so perhaps only with the most recent versions of Plesk is it enabled on fresh install?] We do have an open case for that so that the Plesk module can be updated to send the client IP (case CORE-16812) and our development team is working on that. Unfortunately, I cannot provide an estimated time for completion for this. However, once we resolve cases and push features they are available at our change log. I asked "Since the 8.1.3 version of the Plesk module works fine, shouldn't this be priority since this bug is a regression?" to which they said: "As for the prioritization, what I said could change if our development team determines that a hotfix is necessary or if any conditions surrounding it change (for example: if they determine that the impact on our users, despite the workaround, merits it). I've already tagged this ticket to case CORE-16812, so if a hotfix is released, we will be in touch and provide it to you." And so unless you only have one or two Plesk servers where you can easily apply the workaround, I think the best option -- until they either release a hotfix or an update to WHMCS that includes the fix -- is to simply roll back the module to the version from 8.1.3. Correction, it seems they did release a hotfix after all. I have applied the hotfix and can confirm it resolves the problem. Edited July 2, 2021 by websavers Confirmation of resolution with hotfix 0 Quote Link to comment Share on other sites More sharing options...
papo2414 Posted July 2, 2021 Author Share Posted July 2, 2021 They already answered me from support in WHMCS and they sent me a .zip file containing the solution, thank you very much 🙂 0 Quote Link to comment Share on other sites More sharing options...
