Error 500 when importing csv

Hello all!

I’ve already cracked my forehead trying to solve the problem before I write here. I put on the page the function of importing a csv file with a table, to quickly fill the database. Similar function through Wappler did already several times and everything worked perfectly. But this time faced with the fact that when importing csv gives an error 500:

Hosting I use the same as before (I will remind earlier import on other projects worked perfectly). The error occurs on both complex and simple tables (specially for the test made the import of the table of two fields). The result is always the same: error 500.

Prompt in what a problem?

Thank you in advance for your help.
