Internal server Error 500 when connecting in admin...

[voxlubalin]

Hi, thank you for any help.

I was trying to change something in a module (block "greffer section" I think), and suddenly I get this error , that I meet each time I try to enter the Admin panel : 

Oops! An Error Occurred

The server returned a "500 Internal Server Error".

I put debug mode.
It was question of a file into owlpageTitle, so I temporary desactivated the module.
Ok, but now, the previous message  has been replaced by another (worth one...) and I absolutely don't know what to do...

Thank for your help & lights

(en français, ça sera peut-être un peu plus compréhensif...)

Comment se sortir d'une erreur 500 (internal server) qui empêche soudainement toute connexion à son Admin ?

Je précise que ce message d'erreur fait suite à un tentative de déplacement de module d'un hook à un autre.
Je découvre Prestashop, alors, je triturais un peu... et bien grand mal m'en a pris... me voilà complètement bloquée, en dehors de chez moi

Je suis preneuse de toute aide, merci !

Prestashop version ?

PHP version ?

https://devdocs.prestashop.com/1.7/basics/installation/system-requirements/

Alors :

• Prestashop 1.7.6.8
• Php 7.3

Merci de ton aide

PHP 7.1 or PHP 7.2 and clear cache ( or delete ./var/cache/dev and prod directory)

Thank you, I did it. 

Better because I can put my email and password, but after the login, I'm in front of an error message again...

I've replaced/erased my directory modules, tried differents things, but now the error message is "

Unable to load template 'file:catalog/_partials/miniatures/product.tpl'

Although the file is IN the folder...

Prestashop seems so complicated and hazardous at the same time 🙄
