search for trick to upgrade icu ver in my shared host

[newbie20]

hello 

I have a Prestashop site under 1.7.8.2 ver.
I wanted to upgrade to 1.7.8.7, and then I encountered errors that are related to the old ICU version in my shared host.
I talked to my hosting, and they say, there is no upgrade option by shared host and I should change to private hosting, but I don't want to change to private hosting because of the costs.
is there any trick to bypass the problem?

thanks

Thats in the hand of your host only. Sometimes it helps if you can change the PHP version as this might include the proper ICU. After changing PHP version clean /var/cache to avoid issues.

thanks for your answer.

according to PrestaShop dev docs, the recommended PHP ver for 
prestashop 1.7.8 is  the php ver 7.4 .
and I have the current PHP ver 7.4 installed in my hosting.
as you said, should I downgrade my PHP version by changing from
 presta ver 1.7.8.2 to 1.7.8.7 ?
and if I downgrade my PHP ver then I have no more the recommended PHP ver according to the dev docs.

How do you know this error is related to youre ICU version?

you can also use php 7.3

but i dought this error has something to do with the ICU version.

please try install latest prestashop on a subdomain and check if you get any requirements warning.
