Installing Dashboard Results In 500 Internal Server Error

I'm trying to install the Dashboard onto a new (for me) site but whenever I try to upload it (ver. 4.2.1) I get a 500 Internal Server Error. I uninstalled all the plugins so there's not much chance of conflict, but I'm still getting the error. What else can I try from the admin panel? I don't have access to the server itself.

    Hello Lorie,

    I hope you're well today and thank you for your question!

    The "500 Internal Server Error" in case of WordPress is often caused by insufficient memory limit. Try adding a following line to the "wp-config.php" file of your site:

    define('WP_MEMORY_LIMIT', '256M');

    Make sure that this line is placed above the "/* That's all, stop editing... */" line and then try installing plugin again.

    Let me know please if that solved the problem or if further troubleshooting would be necessary.

    Best regards,

    Hello Lorie!

    In case like this what I suggested is the most essential step that usually solves the issue. In case it didn't help, I would need to investigate it further and that means that I would most likely need to ask you for access to the server anyway.

    You mentioned that you don't have access to the server to be able to edit wp-config.php file. Maybe you cold ask somebody who's "in charge" of the server to do it for you?

    If that's not possible, you could for now try other way:

    - disable all the plugins in site's dashboard
    - then enable WP DEV Dashboard and see if it works and if yes start enabling other plugins back.

    I suppose that at some point during enabling these other plugins site may go down again unfortunately with the very same error but it's worth giving a try. Sometimes enabling plugins "in different order" surprisingly helps too :slight_smile:

    Best regards,
