To run Ueldo WordPress theme without any problems, we strongly recommend you to use always the latest available WordPress version (at least 4.9), PHP version 5.3 or greater, and MySQL 5 or higher. Using always latest WordPress version is important to make sure that all theme features & functionalities will work correctly, and that your website is safe.
PHP contains many settings variables, which can be modified by your server administrators (less often you’ll have access to php.ini to change those variables by yourself). There are few PHP variables which are the most important for Ueldo WordPress theme, like:
At least 8192 for multilingual websites, or at least 2048 for non-multilingual websites
Memory limit variable value shouldn’t be less than 256M.
Server upload max. file size variable value shouldn’t be less than 32M.
For demo templates installation, theme requires also that WordPress uploads folder is writtable (this means that “wp-content/uploads” directory uses correct “chmod” value), and that your WordPress configuration allows the ZIP files upload (this can be changed in “Settings” – “General” tab in your WordPress admin panel).
If you want to use the Import / Export or Restore Theme Options feature, then you should enable OpenSSL library on your server. If it’s not available, please contact with your server administrators.
