I always run into problems when installing things, so this will be for you to install a fresh copy of G-WAN on my server with PHP+security enabled, ready for traffic. You will also need to write exact steps to install so I can reproduce myself.
Shouldn't take long as there are a lot of tutorials out there, I just don't have any experience.
Job needs to be done ASAP.
* typo in main description, I meant to write " install a fresh copy of Varnish"... but if you can do G-WAN too.. even better :)
Im server manager and web security expert, I can help you. If you have more information please contact me, I hope you hire me and thank you very much.
