ive tried deleting the cache folder, restored the backup, then tried the solution i found where i added a tmp folder in the root of the install directory and also modified the relevant file so that it reads tmp/ rather than null

this causes the error page to disappear and show a blank white page instead.

does anyone know whats going on with it? or maybe can point me in the right direction please?

thanks a bunch

SORTED

check local.xml file reflects username and password created in MySQL admin.  this may change, especially if the software updates etc

[TutorialMagento]

You see this error because you set wrong database configuration.

Go to <Magento installation folder>/app/etc/local.xml and edit this file, change database info correctly and the error will disappear.

Solved the problem for me, I have deployed Magento 1 to AWS ubuntu 16.04 and the error pop up because i didn't have database matching the same name as whats show in the folder, 

checked the local.xml file got that name created the database in the ubuntu AWS machine and it worked . 

Thanks

Hi,

Solved in my case (Magento Ver: 2.2.6 over Ubuntu 14.04)

chmod 555 app/etc

Hello Developers

Just go to magento installation directory/app/etc/config.php file and remove the module from array that you were trying to add due to which error occurred.The error will be fixed.

Thanks
