Spaces missing in different PHP version

[zehau]

Affected Symphony version(s) : no idea
PHP 7.4.3
MYSQL 8
Ubuntu 20.04

Hello from Brasil,
I've just started to work with a symphony project.
It works fine in an amazon server, with older versions of php and mysql.
It was moved (not reinstalled), for security reasons, to a new server, that uses this configuration listed above.
The issue is: select fields and buttons in all pages on the new server loses its spaces in its properties.
Example: (ill strip the tags)

label for="estado"
select id="estado" name="estado" class="form-control"

becomes

labelfor="estado"
selectid="estado" name="estado"class="form-control"

Has anybody seen this malfunction and can help me fix it?
It seems easy, but I cant find where to edit and correct it.
Do you think I should reinstall symphony?
I know we are using an old version, but I have no idea which it is...

Thanks in advance,

I've not noticed this behaviour before. Please could you establish the version of Symphony CMS by logging in and navigating to https://example.com/symphony/system/authors/ in the browser, where example.com is the domain on which it is installed. You should see the version number at the bottom-left of the page.

Hi Cylkee, thanks for the answer.
I had posted here the version, but it didn't got registered.
It is 2.3.31.
Thanks a lot,
Zeh

I understand that PHP 7 is only supported on Symphony CMS version 2.7.x.
