It has in htaccess where regex works perfectly with no numbers in the rule, but with numbers not working correctly.
RewriteRule ^([a-zA-Z]{1,20})-to-([a-zA-Z]{1,20})-([a-zA-Z0-9-]{1,30})\/?$ page.php?ti=$1&at=$2&pl=$3 [NC,L]//linha anterior
RewriteRule ^([a-zA-Z]{1,20})-to-([a-zA-Z]{1,20})-([a-zA-Z0-9-]{1,30})-([0-9]{1,3})\/?$ page.php?ti=$1&at=$2&pl=$3&pagination=$4 [NC,L]
The previous line is the page and the second line is the page with pagination. if the third rule, both on the first and second lines, is a-zA-Z- (with the last one at the end) everything works fine, but if it is a-zA-Z0-9- it does not work as it should.
the page URL looks something like this:
www.exemplo.com/bla-to-ble-nome-com-numero-2
page url with pagination
www.exemplo.com/bla-to-ble-nome-com-numero-2-3
nome-com-numero-2 refers to part 3 of the regex
