The simple way is to change the vlan tag on one of the both switches..

Here is a "quick and dirty" workaround, assuming that this is a small environment:

Let's say you choose vlan id 171 to be used on the second switch, and you are using port 1 on both switch for the connection between them. So now configure those 2 ports the following way:
- switch 1, port 1: vlan 71 untagged
- switch 2, port 1: vlan 171 untagged

- If you need to propagate more vlans, you can add them as tagged on the same ports
- This link should be the only one between your switches. Otherwise you'll have to deal with spanning tree / loop protection.
- Mid- and long-term you should definitely sort out your vlan design properly!
