I get an error page in Magento that states:

There has been an error processing your request

Exception printing is disabled by default for security reasons.

Error log record number: [some long number]

What can I do to fix the problem?

  • Is that an Apache error? Find it's error log and look at the last few errors. If you still can't work it out copy them to the end of your question. Commented Oct 3, 2013 at 20:59
  • @clockworkgeek This is a Magento error. It indicates a stack trace has been thrown. Commented Oct 4, 2013 at 1:55

  • You have a MySQL DB Admin issue and this question is close to being closed as far off topic. Once the proper credentials are in your Magento app/etc/local.xml file, you need to start looking elsewhere than Magento. From your MAMP installation may not have been done properly to you didn't properly set up your Magento database and grant proper privileges so that it's accessible. Commented Oct 6, 2013 at 18:07

Error log record number: [ugly long number here]

This is a way too often asked question, so this is one of those WIKI type items.

Your system has run into a problem so egregious that PHP throws a stack trace. It breaks PCI-DSS rules to have the stack trace message automatically show up as a web page as it can expose login credentials and other sensitive data (funny thing, ha ha, several somebodies posted full stack traces containing such sensitive contents over on the Magento Commerce forums over the years). So instead, it gets written to a file named with that ugly long number here you see in the above message.

These stack traces get written to var/report/ unless you've installed Magento in such a manner that it cannot write to the folder due to bad file permissions.

Use your ftp client to display the contents of var/report/ and choose the newest file (ugly long number here) to view the stack trace contents. The first line usually is the most important.

Post the contents of the latest stack trace (obliterate login/db credentials) with your question about how to fix it and you'll get better results.

Now for the concrete problem based on the original question and comments:

And here's what a stack trace from those numbered files stored in var/report/ looks like (site specific path changed to /home/usracct/magento/):

#20 {main}";s:3:"url";s:11:"/magento/";s:11:"script_name";s:20:"/magento/index.php";}

And the first line pretty much states the problem. In this case, it's actually a MySQL issue involving database access.

"SQLSTATE[28000] [1045] Access denied for user 'root'@'localhost' (using password: YES)"

You probably need to check out your database access credentials in app/etc/local.xml and make sure that your db name, db user name and db password are all correctly entered (replace below with actual credentials). The section looks like this:


This is also assuming that the database exists and that 'root'@'localhost' has been granted enough privileges to access the database.

After correcting the above issues, manually clear cache by deleting the mage--? subfolders in var/cache/.

    These stack traces get written to var/report/ What you're showing IS NOT A STACKTRACE, so, what's in the file htdocs/ultraglow/var/report/341074319842 Commented Oct 5, 2013 at 1:47

  • And did you even take the time to read what the error says??? It's pretty clear: you are using an incorrect username/password for MySql.

    There is one last server issue that may be affecting Magento. You have file permissions boogered up on your var/ folder. As this is MAMP and *nix rules apply, chmod -R 777 on var/ so Magento quits storing its cache in the system /tmp/ folder rendering your clear cache null and void. One last Magento issue as well, there must be no other extraneous localsave.xml type files in app/etc/ as Magento reads all .xml files in that folder and includes them in the configuration. Always rename .xml to something like .xml.sv1. Commented Oct 6, 2013 at 18:27
