error 500 in translations

[luismapesca]

Hello, using prestashop 1.7 when trying to enter the translations I get a 500 error, if I debug I get the following:

DEBUG11: 56: 06doctrineSELECT name FROM ps_module WHERE active = 1 CRITICAL11: 56: 06phpUncaught Exception: Unable to load template 'file: helpers / view / main.tpl' DEBUG11: 56: 06doctrineSELECT name FROM ps_module WHERE active = 1 CRITICAL11: 56: 06requestUncaught PHP Exception SmartyException: "Unable to load template 'file: helpers / view / main.tpl'" at /home//vendor/smarty/smarty/libs/sysplugins/smarty_internal_template.php line 195  

the main file following that route does not exist, but I have downloaded a prestashop to see if I could re-upload it and in that route it does not have it as a "series" I would be very grateful if you give me a hand, thanks
