Thank you vvm,I thought it’s not safe set the permission to 777,now we have to do it,include the plugins file and upgrade file,or else we can’t upgrade the plugins.
Thanks Andrew Nevins,it is so kind of you.
Thanks but I’m sorry.
You can design a better one,it’s not too hard.
I don’t know why,but I solved it,I set the Permalink to the “default”,I found it not return to index any more,then I set back to custom Permalink ,it works again.
Thanks both,it’s not about the script and I do have the </form>,I changed the input type,now it works.
