− | If, after changing your PHP version, you encounter an '''Oops''' error or a blank or partially-rendered page, it is likely that there is a file in your installation that is not compatible with the new PHP version.
| |
− | | |
− | This may indicate one of these problems:
| |
− | | |
− | * Syntax Error — A file uses deprecated or removed functionality that is no longer available in the newer version of PHP.
| |
− | * Decoding — A file is encoded with an ionCube® encoding that is not compatible with the newer version of PHP or the installed ionCube Loader® extension.
| |
− | | |
− | To confirm the exact cause of the issue, you must enable error reporting.
| |
− | | |
− | ==Enabling Error Reporting==
| |
− | | |
− | ===Enabling From The Admin Area===
| |
− | | |
− | If you can log in to the Admin Area and navigate to '''Configuration (<i class="fa fa-wrench" aria-hidden="true"></i>) > System Settings > General Settings''', use these steps to enable error display:
| |
− | | |
− | # Go to '''Configuration (<i class="fa fa-wrench" aria-hidden="true"></i>) > System Settings > General Settings''' or, prior to WHMCS 8.0, '''Setup > General Settings'''.
| |
− | # Select the '''Other''' tab.
| |
− | # Check '''Display Errors'''.
| |
− | # Click '''Save Changes'''.
| |
− | | |
− | After error reporting is enabled, retry the steps that previously led to the '''Oops!''', blank, or partially rendered page. More information will display.
| |
− | | |
− | ===Enabling From Your Configuration File===
| |
− | | |
− | If you cannot log in, use these steps to enable error reporting in the configuration file directly:
| |
− | | |
− | # In the WHMCS root directory, edit the <tt>configuration.php</tt> file.
| |
− | # Add these lines at the end of the configuration file, below any other lines but above the closing <tt>?></tt> line, if it is present:<div class="source-cli"> | |
− | $display_errors = true;
| |
− | </div>
| |
− | | |
− | After error reporting is enabled, retry the steps that previously led to the '''Oops!''', blank, or partially rendered page. More information will display.
| |
− | | |
− | ==Common Errors/Resolutions==
| |
− | | |
− | With error reporting enabled, you should see the full error message that WHMCS generates when the problem occurs.
| |
− | | |
− | ===Oops! Something went wrong and we couldn't process your request===
| |
− | | |
− | [[File:Oops_error_page.png]]
| |
− | | |
− | This indicates that a fatal error is occurring. Usually, this is due to these causes:
| |
− | | |
− | * '''Missing PHP Extensions''' — You may see this error if your version of PHP is missing some of the [[System_Environment_Guide#Extensions_2|required extensions]] for WHMCS.<div class="docs-alert-warning">If you compile PHP using EasyApache, you must include both the '''PDO''' and '''mysqlnd''' PHP extensions to allow MySQL® connections.</div>
| |
− | * '''Incompatible PHP Files''' — PHP files using deprecated or unavailable functions may trigger an error page. To debug this, enable error reporting to find the file and PHP error output.
| |
− | | |
− | ===The file was encoded by the ionCube Encoder for PHP x.x and cannot run...===
| |
− | | |
− | You may see an error message that looks like this:
| |
− | | |
− | The file /path/to/file.php was encoded by the ionCube Encoder for PHP 5.6 and cannot run under PHP 7.1 or later. Please ask the provider of the script to provide a version encoded with the ionCube Encoder for PHP 7.1.
| |
− | | |
− | Seeing the above error message indicates that the file was encoded using an older version of ionCube Encoder® that does not include support for PHP 7.1 or later. Contact the original author of the file for an updated version.
| |
− | | |
− | If the file is a WHMCS file, we may no longer maintain or distribute it.
| |
− | * You can identify WHMCS files by checking for the WHMCS copyright notice at the beginning of the file.
| |
− | * Typically, built-in routine updates remove these files automatically. However, permissions issues may prevent removal.
| |
− | * Normally, these files are not in use by the current version of WHMCS and you can delete them.
