I faced a strange issue in my blog. when i publish new articles from admin almost 75% of time it redirect to www.maydomain.com/wp-admin/post.php (Page not found) and nothing saving on the DB.I checked the wordpress forum for this issue they mentioned few things like
1) Disable all the plugins
2) Adding htaccess section
# BEGIN 404 Fix
<IfModule mod_env.c>
#SetEnv MODSEC_ENABLE Off
#PassEnv MODSEC_ENABLE
SecFilterEngine Off
SecFilterScanPOST Off
</IfModule>
#END 404 Fix
3) Increase the memory limits and maximum size on wp-setting.php
All this i have done but the problem remains. Another strange thing i found is this will happen only on server my localhost xampp its working fine.On server sometime its works fine wordpress version is 3.5.2 and plugin are used only recaptcha and seo yoast
I am using meetgaverwp frame work and theme is there any fix for this problem ? The whole day i stuck with this ! :(
