push a forum website diagnostic Forum opened so far, has been a free diagnosis of nearly 1000 sites, and in the promotion of the entry section, every day will produce a lot of problems. The author found that many of these problems are repeated, especially some basic issues, almost every day someone asked. So jianglikun decided to have some very common, we are very concerned about the problem to organize into the article, to facilitate learning. Today, it is said that one of the highest degree of concern, exchange links and do the chain.
