9.6.4.Stable Upgrade Failure

Help! Yesterday I attempted to upgrade my blog to the stable version 6.9.4, which was released two days earlier. Everything seemed to be going okay until I clicked on the install button.

I immediately received a 500 error message that my host' technician diagnosed as conflicting files.

When the technician tried to go to the front of my blog, he got a 503 error message, reporting that the blog was under maintenance.

I was initially able to navigate the blog's dashboard, but no more. Now, all I receive is the same white screen of death.

I downloaded the backup copy of my blog that I saved in September, when I upgraded to 6.9.3 stable, but neither the tech nor I could open it or use it to replace the corrupted blog.

Is there some way to fix this problem? The blog represents 11 years of work.

I've had this problem a number of times with various fixes, and I had the same yesterday and reinstalled 6.9.3 for now as I'm too busy to chase this up.


It seems that something stops the php files from being read, you can see if you can access [install/index.htm] and [install/test] - which has a deafult htm index file.

Do you have ftp access? cpanel access? Remove [/config/umaintenance.php]

Download a fresh copy of 6.9.3 and ftp ?

Missing site address, exact error messages, screenshots, etc. "500" is such a general error that it means nothing.

Even if we suppose "conflicting files" was a correct diagnostic, which are the conflicts?

My site's address is

Fplanque, I was unable to diagnose this problem further before getting a permanent white screen with a 503 error code - under maintenance. However, before clicking the install button, I saw only "okay" after each of the numerous files in the previous step.

I was unable to diagnose this problem further. Each time I clicked an arrow to go back and clicked the install button, I got the white screen with a 503 error message, not the 500 error message I initially received, which I had read to the tech. He diagnosed the issue as conflicting files.

I wish I had thought to take a screen shot of the initial error screen I received upon clicking the install button, but frankly, it's hard to think of that when you see a decade of your life's work replaced by a white screen of death.

Those are good suggestions, amoun. Yes, I still have access to my host account cpanel. There is a backup copy of a 2015 version of my blog on it, but I don't know how to replace the corrupted version with it.

I will see if the other files you mentioned are there. If not, I may still have ftp files on one of my older laptops, but those are from 2008. I had about 300 posts on my blog at the time I tried to unsuccessfully upgrade it on November 27, 2017. Even if I can replace the corrupted version of my blog with the 2015 backup version, I will have to copy and paste 24 posts that it does not have.

There is no way I can replace the missing analytics from the past 2.5 years. Coming at a time when I was attempting to monetize my blog, the loss of that information is irreplaceable.

You shouldn't have lost any of the analytics and posts as they will be in the database, hopefully, you just have to upload the earlier version for now.

As I said I have the same problem, which is far as I can tell is that the php files are not readable, sometimes I've messed with the permissions, sometimes I've ftp's new install folder etc. I have thought, and it was mentioned that maybe there's a delay on the server as once after a second attempt and waiting a while it worked.

I'll try again tonight maybe.
you can get to your test file but as I said it's html not php
gives instructions

doesn't work and gives the server error

Internal Server Error

The server encountered an internal error or misconfiguration and was unable to complete your request.

Please contact the server administrator, and inform them of the time the error occurred, and anything you might have done that may have caused the error.

More information about this error may be available in the server error log.

Additionally, a 500 Internal Server Error error was encountered while trying to use an ErrorDocument to handle the request.

all of which is exactly the same as I've been getting for the last year or two ?????????

Amoun, how long will it take for the system to finish whatever installation process is still ongoing?

Is there any way to access the backup copy of my blog that was made before the installation process stopped the upgrade?

Nov 29, 2017 20:34

Amoun, thank you for trying to help me. I consulted a web developer who helped me revert the blog to a time before I tried to unsuccessfully upgrade the version of b2evolution I am using. My blog is once again up and running.

Fplanque, the 6.9.4 version is not yet stable. Please remove it and work on a fix. Once it truly is stable, I will try to upgrade again.

It's in my profile. Why do you ask?

Dec 01, 2017 02:12

Because it's not in your profile / you're using 2 different profiles.
