I'm getting only 180 posts on my small site. 200 site visitors daily. Still facing fatal error: from memory issues after i visit some admin page or after i edit/add publish.

I'm able to boost the memory limit through wordpress-config.php. But, will it be a lasting solution? When the issue will be happened on so less posts and site visitors it will truly arise when posts could be elevated.

Can anyone tell/suggest which hosting plan could be appropriate to host wordpress blogs?

Or any wordpress plugin like runtime memory manager to ensure that i'm able to host my blog on any server?

Or some suggestions to ensure that i'm able to minimize the memory usage?

I already had deactivated the majority of the plug ins. using gzip response, using wordpress super cache, optimizing DB on weekly basis, and likely to write short posts

Memory Limit 64 Megabytes
