@RealBenihime

PHP's ucwords delimiters parameter (2nd parameter) was added in PHP 5.4.32, 5.5.16 and 7.x

looking at your system info, it seems like your PHP version is outdated the cause of the warning you are seeing.

so try upgrading your PHP version.

Thanks.

If you close this ticket, please inform your people you NOT supporting PHP 5.4.0 like you posting.

You supporting PHP 5.4.32+

Let one thing be clear, thats a HUGE differnce.

Programmer myself for 30 years and seriously impressed about your ignorance, this is a very small bug and can make it work for tons of people.

Even paying for elementor, if i can not get this support, i am gone, very unprofessional, you asking for money and cant even fix the smallest bug.

PS: If you know how to be a programmer? then please upgrade the 5.4 php check to 5.4.32 and dont tell people you support 5.4, know things change something, but if you not willing to fix that function, you gotta change your requirments, let that be clear, things are not for free in my case.

@hmosselaer Thanks for this... I got so busy yesterday I couldn't even analyze the reasoning behind the closure of this issue... I agree that Elementor should either clearly state which PHP versions it supports OR Fix this issue. At the moment I'm unable to convince the organization to upgrade to PHP 7+ and they have close to 500 websites running on their PHP web servers. Unfortunately this error clearly says to me "THIS IS IT, YOU'RE STUCK WITH VERSION 2.4.6"... I truly love Elementor but this is disappointing
