Back office login freezes

[ARI5COL]

Hello! Thank you for watching out for community issues. I´am having troubles with the back office login of my store (https://diegolopezmedina.net/bib/hola/). At first I got error 500. Then I activated the error reporting mode and when reloading the page the login appeared. However, when i entered the correct data the login collapsed and then got frozen; as in the image that I´m attaching. There is no error message, as it should when i activate the debug mode. Although, the following message appears in the chrome console:

Any ideas?, I will appreciate it very much. Greetings
