i did already post this but i'll post it again as perhaps you overlooked it...

i'm having problems i uploaded the 'upload' folder to httpdocs

then
ControlPanel Home > Plugins andProducts > Manage Products > Add/Import Product
Choose file > Product-dbtech_usertag.xml

/var/www/vhosts/dreadsuk.com/httpdocs/dbtech/usertag/includes/class_install.php appears to be missing!

There goes your problem sir, upload the files to (htdocs/forum)

Then import the XML file

I uploaded the 'uploads folder' to htdocs but there were a bunch of files that needed to me moved into the right places manually.

Its now installed but a few issues..

When user gets a mention notification, and user clicks
Notifications > New Mentions
it goes to 404 error

same with taggin statistics
/usertag.php?do=statistics

Its also not clearing the mentions notifications counter.

Have 404 errors everywhere now :(

You do not need to upload some files manually to locations. Just upload the contents of the "UPLOAD" folder to your "htdocs/forum" destination. It will automatically overwrite the older files and replace them.

On the forum, you have to tag the users with their exact name being case-sensitive. @Abc and then afterwards @Abc should take you to their profile.

Check this post for instance, that's my board.

i did that but it didn't work. Moving folders manually did.

Just putting the uploads folder to htdocs didn't put the right files in the right places hence it looking like the file was missing when it was actually in the folder, just in the wrong place.

Thats not the issue. the actually taggin works fine in terms of the tag itself. user is notified, its the notification link in notifications that isn't working

OK, i fixed it. The issue for anyone else that has a similar problem is that the file usertag.php stayed in the folder 'uploads' when it needed to be moved out of that folder and place in the root folder, same as forum.php

I'll mark as installed now and offer help anywhere i can with anyone else struggling.

Still pretty new to vb, but starting to get the hang of it.

Massive thanks to all the contributions from everyone and i hope to 'pass it on' :)

one thing i can't find is admincp/index.php

It doesn't seem to be in the folder anywhere

Have you renamed your ACP?

Not to my knowledge. how would i check this?

What is the name that appears in your browser when you are in the ACP
