Blank Main page after updating to 3.3

To be specific, here is the error that I get:

Server error
The website encountered an error while retrieving https://libraliyya.org/wp-admin/admin.php. It may be down for maintenance or configured incorrectly.
Here are some suggestions:
Reload this webpage later.
HTTP Error 500 (Internal Server Error): An unexpected condition was encountered while the server was attempting to fulfill the request.

I’ve read many solutions for this problem by googling it, but none worked for me.

What worked for me was setting CHMOD permissions for ALL files and folders to 755.

@mitheithel; That’s highly unusual and hints at a bizarre server set up.

@ihussein: Try:
– switching to the Twenty Eleven theme by renaming your current theme’s folder in wp-content/themes and adding “-old” to the end of the folder name using FTP or whatever file management application your host provides.

– resetting the plugins folder by FTP or phpMyAdmin.

– re-uploading all files & folders – except the wp-content folder – from a fresh download of WordPress.

– re-running the upgrade via wp-admin/upgrade.php

@esmi: Thank you. I am done with steps 1 and 2 but am worried about step 3. If I upload the entire WP 3.3, that wouldn’t affect my blog posts, pages, etc content and will also retain the previous blog layout when I switch back to my normal template?

Also, since in step 1 I renamed the themes folfer to themes-old, I shouldn’t worry about the fresh WP upload since it won’t replace the already renamed themes directory, right?

Finally, after step three, should I delete the newly uploaded themese directory and rename the old themes-old directory back to themes?

Thanks a lot.

Also, after doing step 2, I can see my dashboard fine now. Just no themes at all I am guessing because I renamed it to themes-old.

Please re-read the steps I posted above. Your site’s content is stored in your database and will not be affected by an upload of fresh files outside of the wp-content folder.

OK, thanks. I have gone through all the steps exactly as you said. But now the site gives a blank page: libraliyya.org. Is there something else I need to do? Do I rename the themes directory to just themes instead of themes-old? Appreciate you help.

But when I renamed the directory to themes instead of themes-old, the site is back on but I am now at version 3.2.1 and it is back to saying to upgrade to 3.3. Should I go ahead an upgrade?

Rename wp-content/themes-old back to wp-content/themes. Then switch to the Twenty Eleven theme by renaming your current theme’s folder in wp-content/themes.

@esmi:

The theme on the front page is Caroline, though in the themes section it claims that the current theme is Twenty Ten. Other than that discrepancy, it still says upgrade to 3.3. How do I proceed from here? Thanks for your patience.

Assuming this is https://libraliyya.org/, you are using Coraline.

Right. There was some missmatch. Now it seems fine. Should I go ahead and now upgrade to 3.3? Or will I face the same problem as I did this morning?

Try:
– switching to the Twenty Eleven theme by renaming your current theme’s folder in wp-content/themes and adding “-old” to the end of the folder name using FTP or whatever file management application your host provides.

– re-uploading all files & folders – except the wp-content folder – from a fresh download of WordPress.

– re-running the upgrade via wp-admin/upgrade.php

@esmi: IN step 3, that fresh WP download, should it be 3.3 or 3.2.1? I assume the latter since in step 4 you recommend re-running the upgrade.

Also, in step 2, when I click on the provided link and choose to rename the plugins folder should I switch back to plugins from plugins.hold after step 4 above?

should it be 3.3 or 3.2.1?

3.3 – since that’s what you were trying to upgrade to.

should I switch back to plugins from plugins.hold after step 4 above?

Leave that until after the upgrade has completed successfully and your site is running again.
