[IndexError]

Hello guys, 

I have using Amazon AWS, and wasnt having any problem, but in order to save some money I tried InfinityFree and I'm getting this error.

The error:

I think thats enough and hope somebody can help me out

[iRedds]

->get() can return boolean value

[IndexError]

->get() can return boolean value

Yeah, so what happened is that, it was an database with mysql problem, which it closes the connection in the middle of the command..
so ->get() wasnt receiving anything, and apparently Infinityfree doesnt not let change the time out of the connection.

Thanks anyways
