After a migration, query-string URLs may work while normal post permalinks return 404. A damaged or missing WordPress rewrite block is a likely cause, but replacing the entire .htaccessfile can erase unrelated rules.
Preserve the complete file first, then regenerate only the WordPress-managed section for the current installation and permalink structure.
What it means
Regeneration recreates the rewrite directives that WordPress places between its BEGIN WordPressand END WordPressmarkers. Saving the Permalinks screen can write this block when the server and filesystem allow it.
The process does not reconstruct directives added by a host, security policy or administrator. Multisite and subdirectory installations also require rules appropriate to their actual layout.
A realistic WordPress example
A migrated site has a truncated WordPress block followed by custom access restrictions. Pasting a generic complete file would make posts work but remove the restrictions.
The administrator saves the original, extracts the custom section and refreshes the permalink rules from WordPress. The custom directives remain outside the regenerated markers.
Why it matters and when to use it
Correct rewrite rules route friendly URLs to WordPress while allowing existing files and directories through normally. Regeneration is appropriate when permalink requests fail and evidence points to the WordPress block.
It will not fix Nginx configuration, a wrong document root, disabled overrides or missing Apache rewrite support. Confirm those conditions before repeating the save action.
A straightforward route for beginners
- Copy the entire active
.htaccessfile and note its permissions. - Identify and preserve every section outside the WordPress markers.
- Confirm the site URL, installation path and current permalink setting.
- Open Settings, Permalinks and save the existing structure once.
- If WordPress cannot write, copy only the generated WordPress block through the supported file-management route.
- Test the home page, a post, an archive, a missing URL and the preserved custom behavior.
The advanced route
Compare the generated base path and rewrite target with the deployed layout, especially for subdirectory and multisite installations. Check mod_rewrite, AllowOverrideand the Apache error log when the block is present but ignored.
Use a query-style URL as a control to distinguish WordPress availability from rewrite failure. Keep custom redirects and security directives outside the WordPress markers because WordPress may replace the marked content later.
Risks, common mistakes, backup, and rollback
The main mistake is deleting the whole file in order to rebuild one managed block. Generic rules from another topology can also create loops, expose protected paths or route requests to the wrong directory.
Rollback restores the exact saved file, including its original ownership and permissions. If regeneration fails, stop before making repeated edits and resolve the server or filesystem constraint directly.
How AIOWS helps:
AIOWS Htaccess Editor
AIOWS Htaccess Editor can provide a WordPress-side place to review the current file and make the supported correction while preserving visible custom sections. This is useful when only the WordPress rewrite block needs attention.
Save an independent copy before editing, keep custom directives outside the WordPress markers and verify several request types after the change. The generated rules must match the current installation rather than a sample from another site.
The editor cannot enable Apache modules, change AllowOverrideor make Nginx read .htaccess. Those server-level conditions must be corrected by the appropriate administrator or host.

Conclusion and recommended route
Back up the complete file and regenerate only the WordPress permalink block for the deployed site. Preserve custom directives and investigate server support if the fresh block is still ignored.
