Thank you!
I’ve found out the reason!
The plugin “Google Sitemap Generator for WordPress v2 Final” causes this problem,when I disabled this plugin, the blog turns to normal,when I enable this plugin, the “504 gateway error” will display.
So just DISABLE the “Google Sitemap Generator for WordPress v2 Final” plugin, or use another sitemap generator plugin.
I still can not find out the reason of this problem,and it’s impossible to change a new router for me.All I can do is use the wordpress’s text-editor to post.
Thank you!
