Cannot Connect Database When Upgrading from v1.5.0 to v1.5.5

[lat9]

PHP version 5.5.38 (Zend: 2.5.0)

line 64: $this->link = mysqli_connect[$zf_host, $zf_user, $zf_password, $zf_database, (defined('DB_PORT') ? DB_PORT : NULL], (defined('DB_SOCKET') ? DB_SOCKET : NULL));

Zencart v1.5.5e, does that tell you which one? I had no idea there were so many

That line is (somehow) different than the as-shipped version; it should read:

$this->link = mysqli_connect[$zf_host, $zf_user, $zf_password, $zf_database, (defined('DB_PORT') ? DB_PORT : NULL), (defined('DB_SOCKET') ? DB_SOCKET : NULL));

That change should correct your issue, although I'm pondering how the character was changed in the first place!

I was able to get "Sorry! There seems to be a problem connecting to our database. Please give us a few minutes to remedy the problem. Thank you." screen instead of a blank screen when I changed the top of my configure.php files from this:

to this:

The HTTP 500 error remains for the admin page. There is something I missed somewhere and my database isn't connected. Where is the 'Apache error log?'

Thank you, I corrected line 64. Now what?

Thank you, I corrected line 64. Now what?

Check your logs directory (different than and not your apache logs) and see what the latest (most recent) myDebug file is and it's contents.

Also, from where did you get your updated fileset? Was it a fresh install as downloaded from this website or was it some sort of auto-installer?

Sorry to say, but the change in the above comments has no effect on operation, so wouldn't have really solved anything.

Content placed between /* and */ while within code is basically ignored by the program. It helps those individuals that read it, but it doesn't alter basic operation.

I downloaded the 1.5.5 from the zencart website and uploaded to the subfolder on my site. My database is a backup of my existing database that I copied and uploaded as a new database via phpMy Admin. Now there's a problem on line 62. How to I figure out what it's supposed to read? When I looked at the original download on my PC, it's the same as the error line so I don't know what to change it too.

Try checking against the github version of 1.5.5.e: https://github.com/zencart/zencart/tree/v1.5.5e

Also when was the download performed (if download itself came with bad information that data point would help the core group possibly track down an issue). Please include some correlation of timezone and time if able (should show the download time as the date the file was saved to your computer and you know what timezone you are in and can maybe base it off of GMT if so desired.)

Thank you, that was helpful, but the line is still the same so I don't see an error. I still have the database connection problem. Where else can I check for errors?
