PHP Notice: set_time_limit() has been disabled

set_time_limit() has been disabled for security reasons

I have run into this error, the logs gave me this:

2016-03-22 10:17:44 - PHP Notice: set_time_limit() has been disabled for security reasons in /membri/pvstoreopen/front/admin/model/tool/export_import.php on line 6654

line 6654 looks like this:

set_time_limit( 1800 );

Any help?

That error message looks pretty self-explanatory: you have a function in your script (set_time_limit) which is not available, due to security restrictions.

If uou are the author of the script, you should be able to refactor and avoid that function.
Otherwise, you can either ask the author or post the code here, so we can find a solution.

PS: You asked your question in English and so I replied, but I wonder why using English here in the Italian forum.

Please use the international forum.
