This is an English speaking only site. If you want help maybe you should use google translator and then edit your topic.
@James, FYI this post actually says:
You can change it yourself depending on the group you are in. Otherwise you are right a Staff Member has to change it.
Just be patient, a Staff Member will reply to you when they get a chance too.
Go into your forums main directory and edit the config global php file with the new database information. This will solve your database password issue.
The licence is in the core_sys_conf_settings database table. Should be around line 136 in the table.
That is no reason to down vote someone. Sometimes it takes more then one post to resolve issues, you should know this.
Thank you for sharing this. I was able to use this to edit just the main forum area titles which is what I had been trying to find how to do. All I did was used the first data-forumid code and repeated that with the number for my forum areas and left the other code out for the sub forums (I had to do that as it didn't appear to work on the deflection 4.4 theme for some reason). But still it is great to change each forum title area with it's own color.
I am not sure on this one to be honest, but it could be something to do with the friendly urls as this is mentioned in the first line of the error. Do you have friendly url enabled for pages?
Go to your ACP -- Member Settings -- Profiles -- Scroll down to Group Formatting then select Global and Save.
Then also go to Support -- Something isn't working to clear your cache. See if that brings it back.
You change it through your cpanel or web host admin panel. But since it appears you are using a free web host, if you don't have access to cpanel ask your web host to change it for you.
Run the update again and see if that has helped. Or send me the site to your site and I will take a look for you.
Also, try on php v 7.1. One of my sites need 701 as it wouldn't work on 7.2 as well.
