    Internal server errors (error 500) are often caused by plugin or theme function conflicts, so if you have access to your admin panel, try deactivating all plugins. If you don’t have access to your admin panel, try manually resetting your plugins (no Dashboard access required). If that resolves the issue, reactivate each one individually until you find the cause.

    If that does not resolve the issue, try switching to the Twenty Fifteen theme to rule-out a theme-specific issue. If you don’t have access to your admin panel, access your server via FTP or SFTP, navigate to /wp-content/themes/ and rename the directory of your currently active theme. This will force the default theme to activate and hopefully rule-out a theme-specific issue.

    If that does not resolve the issue, it’s possible that a .htaccess rule could be the source of the problem. To check for this, access your server via FTP or SFTP and rename the .htaccess file. If you can’t find a .htaccess file, make sure that you have set your FTP or SFTP client to view invisible files.

    If you weren’t able to resolve the issue by either resetting your plugins and theme or renaming your .htaccess file, we may be able to help, but we’ll need a more detailed error message. Internal server errors are usually described in more detail in the server error log. If you have access to your server error log, generate the error again, note the date and time, then immediately check your server error log for any errors that occurred during that time period. If you don’t have access to your server error log, ask your hosting provider to look for you.

    Thanks for the advices.

    Renaming the plugins folder and activating them back worked for me.

    The problem is, there’s nothing wrong with the plugins. I’ve re-activated them all and the wp-admin works fine.

    I guess something wasn’t complete in the process of update and re-activating plugins worked for me.

    At least it’s fixed now. 🙂

    The same problem here…. because only Plain links work on the permalinks settings in wp 4.4.1, I rolled back to 4.4. to get my BBPress working as it won’t work on plain links. Now I find that I am getting this internal server error every time I try and edit a page etc.

    As I don’t find that CODE IS POETRY…:-) I am seeking urgent help…. This is a portion from the error log if it helps
    /wp-includes/load.php) [function.require]: failed to open stream: No such file or directory in /home/alpujarr/public_html/newsletter/wp-settings.php on line 21

    This line states ‘ require( ABSPATH . WPINC . ‘/load.php’ ); ‘

    Can anyone help????
    Very frustrated……..

    Sounds like you missed a file when you rolled back.

    Try downloading WordPress again, access your server via SFTP or FTP, or a file manager in your hosting account’s control panel, and delete then replace your copies of everything on the server except the wp-config.php file and the /wp-content/ directory with fresh copies from the download. This will effectively replace all of your core files without damaging your content and settings.

    Some uploaders tend to be unreliable when overwriting files, so don’t forget to delete the original files before replacing them.

    That will update you to 4.4.1 again, might as well see if you have the same permalink problem again. If you still do, you can get 4.4.0 from

    Keep in mind that 4.4.1 included security fixes for vulnerabilities which are now publicly known.

    Hi, thanks James for your suggestion which I have done and now I have 4.4.1 installed and BBPress and still cannot post new topic because I have to have Plain links instead of date and name links…. so I either can’t post topics or see my front page!
    It’s driving me mad….
    What’s the point of a forum if you can’t post….?
    Any suggestions?

    Try re-saving your permalink structure at Settings/Permalinks in your admin panel. If WordPress cannot automatically edit the .htaccess file, it will provide manual instructions after saving.

    Does it affect blog posts and pages too, or just forums?

    Yes, I can save the permalink settings but if I save PLAIN permalinks I cannot post topics and if I save date and name permalink or any any other, my web site won’t open on my static page, (page not found) but I can post topics!
    Posts and pages are ok, no problem. It’s obviously a bug between BBPress and WP.
    You can look here….

    In that case, I recommend asking at so the bbPress developers and support community can help you with this.

    I have now deactivated BBPress and am tearing my hair out getting deeper and deeper in the mire…. it’s not easy for a 72 year old…:-)

    Is it possible someone could take a look and advise me what I can do to get this site running correctly. Some pages load to the subfolder others don’t load as they don’t show the subfolder and i get a 500 error, sub folder ‘newsletter’
    To be honest right from the start i could only use plain permalinks after installing which was strange. I have now updated to 4.4.2 but no difference.
    What should the htaccess file have in the newsletter sub folder? My site is on a multihosting site, Hostek, where I have other wp sites without problems.
    ‘newsletter’ subfolder relates to the main holding domain as above.
    I did use ‘Newsletter’ as the subfolder which I now know was a mistake and Hostek, FIXED it but caused other problems too…….where can I go from here?

    Can anyone help and advise…..PLEASE?

    I am getting a HTTP ERROR 500 error. I accidentally deleted something from my theme and now I can’t log in at all.

    I am having the same 500 error problem with my wordpress site. I can’t get to my dashboard and don’t have the technical knowledge to solve the problem. Is there someone that can help me fix it or do it for me?

    My site is The site is coming up okay, as of now, but I get the error when I try to login to my dashboard.


    i was stuck in the ”upgrade.php” cycle and after deactivating all the plugs-in, renaming the .htacess file I was still in stuck.

    I found this procedure useful:
    Check file “/wp-includes/version.php” $wp_db_version = [some number value] against the database options table’s options_value. They should have the same number value. If those numbers are not the same, change the value in the options table to match the value in the version.php file.

    This procedure worked for me and now all works fine even after reactivating all the plug-ins.
    Kind regards,
    Marco – StockTrader

    @marco That’s rather dangerous since the version that the DB thinks it is (and probably actually is) needs to match what the code is expecting. Forcing them to be the same doesn’t suddenly change the DB structure.

    I am not a WP expert but what I’d suggest is;

    Find out what the DB thinks it is (check db_version entry in the options table against )

    Download that version of WordPress.

    Manually install that (FTP up the files after deleting wp-admin and wp-includes)

    Trigger the upgrade from within the admin area.
