This form is for reporting run-time errors from Wikimedia production services (see examples below). To report a bug or other problem you encountered while using the software, use **[New Bug Report](https://phabricator.wikimedia.org/maniphest/task/edit/form/43/)** instead.
### Step 1: Request URL
{F28499945 height=100}
### Step 2: Request ID
{F28499957 height=65}
//(Alternatively, if you are reporting this error code from Logstash, look for the `reqId` field.)//
### Step 3: Trace (optional)
If you are a developer with access to Wikimedia Logstash, then be sure to report the stack trace as well. All PHP errors, exceptions and fatals have stack traces reported to Logstash. Including "PHP Notice" and "PHP Warning" errors from MediaWiki. If you don't see them, be sure to look for the instance of the error with `type:mediawiki` and not `type:syslog`.
