Sometimes it's necessary to run some tests or debug specific issues in Blesta. Here are some common things you may need to do, or may be instructed to do by support, when something goes wrong.

Check PHP CURL, outbound TLS Version

Blesta integrates with many 3rd party services and it may be necessary to ensure that your server is capable of making a TLS connection with certain minimum requirement. Here's sample code you can place on your server and access in your browser. It will return the most modern version of TLS that your server is capable of negotiating. If it say TLS 1.1 and the service you are connecting to requires TLS 1.2, then it will explain why a connection is not possible.

    $ch = curl_init(''); 
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 
    $data = curl_exec($ch); 
    $json = json_decode($data); 
    echo "<pre>TLS version: " . $json->tls_version . "</pre>\n";

Copy the code into a text file named curl-check.php and upload to your Blesta installation directory. Access in your browser and it will display the most modern TLS version supported. e.g. TLS version: TLS 1.2

Enabling Error Reporting & Debugging

To enable error reporting, edit /config/blesta.php and change Configure::errorReporting(0); to Configure::errorReporting(-1); You may also wish to enable System Debug. To do so, change Configure::set("System.debug", false); to Configure::set("System.debug", true);

Do not leave System.debug enabled

Be sure to change these settings back when you are done, especially System.debug. Leaving System.debug enabled can cause other issues and may become responsible for other errors within the system.

Checking Error Logs

Starting with Blesta 4.1.0, errors are logged to disk by default. To see if your system is logging, check the path under Settings > System > General > Basic Setup for "Log Directory". This should be the full system path to your logs directory, and it should indicate to the right of the field that it is writable.

Then, navigate to this directory on your server. You should see some log files, including:


Support staff are mostly interested in the error and emergency logs, but depending on the issue the other logs may be important. The error log contains PHP exceptions, and the emergency log contains Blesta errors. Find the files with the most recent date, and open them to find the errors. If the error is reproducible and you have SSH access to the server, you can "tail" the log files while reproducing the error to more easily find what you need. For example: tail -f general-*.log will tail all of the log files at once.
