>> Parse error: syntax error, unexpected '[' in /var/www/ahk/wp-content/plugins/openid-connect-sso-by-gluu/gluu_openid_oxd_settings.php on line 109
If you remove that '[' from php file, is that resolved?
>> 1. Can you replicate the php parse error with version 3.0.1 and can you fix this error?
We will try to reproduce the issue and fix if required.
>> 2. Should I wait with the update of the working connection because this will potentially break the connection?
Up to you, as you have already one working condition with 2.4.4.
>> 3. Can I use the old version of your plugin in the production environment of the new client and upgrade later once issues mentioned have been resolved?
Wont' be a bad move, please feel free to check. But Jajait might confirm.
>> 4. Do you need access to a Wordpress site of ours to speed up the process of testing and fixing?
We are unable to provide that level without [VIP subscription](https://www.gluu.org/gluu-server/pricing/).
