I’m having an issue where UpdraftPlus’ vendor files collide with the ones from another plugin. The other plugin is using the same crypto library which results in redeclared classes.
PHP Fatal error: Cannot declare class Crypt_Rijndael, because the name is already in use in /wp-content/plugins/updraftplus/vendor/phpseclib/phpseclib/phpseclib/Crypt/Rijndael.php on line 1050
As a quick fix I renamed all occurences of the crypt libraries. But I don’t wanna do this with every update.
Maybe this could help: https://github.com/TypistTech/imposter
