Can’t Login, No WP-Login.php Page

  • I just tried to login to my WordPress site via /wp-login.php and I get this error in Firefox browser:

    “The page you are trying to view cannot be shown because it uses an invalid or unsupported form of compression.”

    I had just previously updated some plugins (WP Super Cache, etc.) and made some changes to my sitemap.xml page. I had deleted the cache and logged out and got the error above.

    When trying to login using Google Chrome I get the following error:
    The webpage at /wp-login.php might be temporarily down or it may have moved permanently to a new web address.

    Error 2 (net::ERR_FAILED): Unknown error.

    All my other posts and pages are accessible to view, the wp-login.php page is the only one that doesn’t work. Thus I can’t login.

    If you have any ideas on how to fix this I would greatly appreciate your input. Thanks!

    Okay, just tried logging on using my phone and the wp-login.php page loaded and I was able to login.

    Also tried going through proxy and the page loaded again.

    Does anyone have any idea why I would be able to see the wp-login.php page using my phone’s browser or by using a proxy but I’m not able to using any computer’s browser?

    I thought it might be a plugin problem so I renamed my “plugins” folder but that didn’t work.

    I think the problem might be with WP Super Cache or my theme.

    Just a quick update, I was able to login using my G1’s browser and updated all my plugins that needed it, including the ones that were disabled. Then I deleted the cache and voila! The wp-login.php page was accessible again. Not sure why this happened but at least it is working now ??

    Hey vizionquest – thanks for the info. I am having a similar problem. Off to try logging in on a different browser.

    Update: I tried logging in on IE and instead of the blank screen I get with Firefox, I got this message:

    The website cannot display the page
    HTTP 500
    Most likely causes:
    The website is under maintenance.
    The website has a programming error.

    What you can try:
    Refresh the page.

    Go back to the previous page.

    Help! How do I solve this?

    More information

    This error (HTTP 500 Internal Server Error) means that the website you are visiting had a server problem which prevented the webpage from displaying.

    For more information about HTTP errors, see Help.

    I had to do modify my “/wp-content/cache/.htaccess” file after I installed. I also had to remove
    ob_start("ob_gzhandler");
    From the top of the header file for my theme. I had added it there before I knew about the WP Super Cache. It is PHP’s way of Gzip compressing content. I have the htaccess modifications you can try listed on my site here:

    If I am reading this post correctly then we have had this as an ongoing problem on a number of our blogs for ages. It seems to be random, but thankfully there is a fix. We posted a walkthrough here:
