Our website runs an older Joomla version (maybe 1.7.x) with some common plugins/modules and needs to be updated immediately because of security issues.
You'll be given ftp access to our LAMP machine and all needed information. Layout and content of the website should remain unchanged.
Start: As soon as you can. Finish: As soon as you can.
I'd like you to have proven experience with Joomla installations as well as modules and plugins.
