Fixing WordPress Errors with Simple Code Tweaks

WordPress is powerful, but sometimes, things break. Instead of relying on plugins for every fix, here are some simple code-based solutions to common WordPress errors.

1. Fix “Allowed Memory Size Exhausted” Error

Issue: Your site crashes with an error saying, “Fatal error: Allowed memory size of XXXX bytes exhausted.”

Solution: Increase the PHP memory limit by adding this to wp-config.php:

define('WP_MEMORY_LIMIT', '256M');

If this doesn’t work, add this to your .htaccess file:

php_value memory_limit 256M

2. Fix Maximum Upload File Size Error

Issue: You’re unable to upload large media files due to a size limit.

Solution: Increase the limit by adding this to php.ini (if your host allows it):

upload_max_filesize = 64M
post_max_size = 64M
max_execution_time = 300

If you don’t have access to php.ini, add this to .htaccess:

php_value upload_max_filesize 64M
php_value post_max_size 64M
php_value max_execution_time 300

3. Fix “Too Many Redirects” Error

Issue: Your site keeps redirecting in a loop, causing the “ERR_TOO_MANY_REDIRECTS” error.

Solution: Disable forced HTTPS in wp-config.php:

define('FORCE_SSL_ADMIN', false);

Or, reset your site’s URL settings using functions.php:

update_option('siteurl', 'http://yourwebsite.com');
update_option('home', 'http://yourwebsite.com');

4. Fix “Pluggable.php File” Errors

Issue: You see an error mentioning pluggable.php, often after installing a new plugin.

Solution: This usually happens due to extra spaces in wp-config.php. Open the file and ensure it starts with <?php and has no blank spaces before or after the closing ?>.

5. Fix “Session Expired” or Login Issues

Issue: You keep getting logged out, or you can’t access the admin panel.

Solution: Update the cookie settings in wp-config.php:

define('COOKIE_DOMAIN', $_SERVER['HTTP_HOST']);

If that doesn’t work, clear your browser cache or try logging in via wp-login.php instead of wp-admin.

6. Fix WordPress Not Sending Emails

Issue: WordPress contact forms or notifications aren’t being sent.

Solution: Set up SMTP using functions.php:

add_action('phpmailer_init', function($phpmailer) {
    $phpmailer->isSMTP();
    $phpmailer->Host = 'smtp.yourdomain.com';
    $phpmailer->SMTPAuth = true;
    $phpmailer->Username = 'you@yourdomain.com';
    $phpmailer->Password = 'yourpassword';
    $phpmailer->SMTPSecure = 'tls';
    $phpmailer->Port = 587;
});
