You hosting provider have cPanel? try install Mautic from cPanel.  
Also try download again the Mautic from [https://www.mautic.org/download/](https://www.mautic.org/download/)  
i just install another instance for a client and works great!

@ninjoan Thanks for your reply. but my hosting provider doesnt have cPanel & i have already uploaded the stable version of mautic 1.2.2 from their download link as you mentioned above.

it is getting installed on local without any problems. but when i put it on server it gives me 404 error. i am not sure whether it the issue of htaccess provided in mautic software or server htaccess.

or may be the setup issue… but it has only 5% chances… because its working on local.

please provide any solution if you have any

Try to clear your cache (delete app/cache folder).

It’s not the tmp folder in the Mautic root folder. It’s the tmp folder in your server root folder:

> [@](#):
>
> /tmp/sess\_93788d18d89ce8d3aa76984a2fcb6a2e

I have no idea what is going on or how to solve it. Never happened to me. You can try to [google the error message](https://www.google.cz/search?q=Warning%3A+SessionHandler%3A%3Aread()%3A+open(%2Ftmp%2Fsess&oq=Warning%3A+SessionHandler%3A%3Aread()%3A+open) to learn more.

I’m using DigitalOcean. A virtual server which I’m maintaining. I wouldn’t recommend this option for “normal people” who doesn’t want to spend days learn how to maintain a server. Maybe check out [mautic.com](http://mautic.com) if it will fit your needs.
