Considering what seems to be no reason for changing our plan, we had no way out but to stick to the old one.
这个句子有两个错误：
1. what使用错误，应改为there；
2. seems使用错误，应改为seemed，保持句子的时态一致。
即改为：Considering (that) there seems to be no reason for changing our plan, we had no way out but to stick to the old one.
句意：考虑到似乎没有理由改变计划，我们别无选择，只得坚持原来的计划。

Considering (what) seems to be no reason for changing our plan, we had no way out but to stick to the old one.
参考译文：考虑到/鉴于似乎没有理由改变我们的计划，除了坚持原来的计划，我们别无选择。
解答:What为融合型关系代词引导宾语从句，做前面considering的宾语成分。
备注(1):what=the thing that相当于Considering the thing that seems to be no reason for changing our plan, we had no way out but to stick the old one.
Considering (what) seems to be no reason for changing our plan, we had no way out but to stick to the old one.
备注(2):what seems to be no reason for changing our plan为宾语从句作considering的宾语。
