Have you tried:
– deactivating all plugins to see if this resolves the problem? If this works, re-activate the plugins one by one until you find the problematic plugin(s).
– switching to the default theme to rule out any theme-specific problems?
– resetting the plugins folder by FTP or phpMyAdmin? Sometimes, an apparently inactive plugin can still cause problems.
esmi, now I reset the plugin folder, but not work yet…
Odd.
Does this happen too if u switch to other theme e.g Default theme? Update permalink does it work? check htaccess file, error log?
No error log.
I was change theme but not work too.
htaccess file looks ok.
If u logged in, u can view the page? I see that this only happen on single post, and view page. View archives, category no problem.
Have u try regenarate the permalink in Settings?
Yes, I tried regenarate the permalink, but the not work…
Have you checked to see if the post somehow became private?
In dashboard the posts are not selected how private.
Can you switch to using the default, permalinks and see if that helps?
Hi esmi, with default permalink the error change:
Default permalink error: Sorry, no posts matched your criteria.
Pretty Permalink (day and name) error: Error 404 – Not Found
Thanks for all.
The fact that this is only affecting single posts and Pages still makes me think that this is a template or plugin issue.
Have another problem… the new posts are created with same ID (1).
