[SOLVED] cant install plugins

Hi everyone .. I'm new to bfa forums.
Montezuma is a great theme and a great gift to wordpress.

I have a little query , it may sound silly, but its really getting on my nerves.

I cant install plugins for my website. I installed 2 or 3 , and now they just wont install.
I can't upload them.
I cant install them, after searching for them.
I cant install them from my web file manager.
My internet speed is also good.
I just can't.


whenever I try to install it, I get the following message :

Fatal error: Maximum execution time of 10 seconds exceeded in /home/a3903197/public_html/wp-admin/includes/class-wp-filesystem-direct.php on line 172

any help, would be really appreciated
thanks
