Out of memory error

Hi All, 

There are more than 700 members at our community, I uploaded TiddyPixExt plugin, it was working fine till I get this error 

 

Fatal error: Out of memory (allocated 62914560) (tried to allocate 46 bytes) in /home/mtecuk/public_html/tuacl.com/community/engine/lib/metadata.php on line 33

 

I wonder what to do with it, I increased the php size to 128, its not working

I deleted few plugins directly from FTP its not working 

I uploaded DIASABLED and stoped all plugins, then I went to ADMINISTRATION of my account clicked on TOOLS and it gave me this message

 

Fatal error: Out of memory (allocated 62914560) (tried to allocate 43 bytes) in /home/mtecuk/public_html/tuacl.com/community/engine/lib/metadata.php on line 33

 

What to do with it, please reply
