OK I will not ask, but ugh!
Download the install package from:
https://github.com/elkarte/Elkarte/releases/tag/v1.1.8
Starting from 1.1 the install and upgrade packages were unified, so the same package will be used for both install a new forum and upgrade an existing previous version of ElkArte (e.g. 1.0).
Some basic instruction- Backup the site and the database, no excuses
- Put the site in maintenance mode
- Uninstall any addons/packages you have. Uninstall just the packages, leave the database data.
- If using a custom theme, set the site back to the default theme
- Upgrading from 1.0: Overwrite all the existing site files with those in the package.
- Run install/upgrade.php by pointing your browser to the site, it should bring up the upgrade screen automatically, but if not, point it to install/upgrade.php
- Follow the update steps
- Delete any old files left behind by the upgrade, I think that is only Markasread.controller.php from the /sources/controllers/ directory. But do not delete Markread.controller.php
- Admin Login
- Upload new versions of the packages you have, and install them
- Try the old theme, see if there may be an update, if not prepare to do some work to get it fully compatible. I would just allow the old theme as user selectable but not the site default until you know it works.
- Check / Update your custom profile fields as the 1.0 to 1.1 will need some tweaks
- Take it out of maintenance mode
That should get you going in the right direction ... Ask if you have problems with the steps.
