Hi, friends,from yesterday, when i sign in Expertscolumn, the following words will appear: You must enable the PECL memcached or memcache extension to use memcache.inc. What does it mean? How can i enable PECL memcached or memcache extension?

I got the same message yesterday. It a problem that happens most probably if there is new software/file installed in a computer. I am not sure whether I need to do something or the Expertcolumn website is the one having the problem.

Hi, it didn't appear any more. Well, i think it is the problem of the website, not problem of ours. I am glad it is over, anyway, expertscolumn is a good site.
