Best practice
Avoid using the phrase "but was because". Instead, rephrase your sentence using alternatives like "but that was due to" or "but it was a result of" for improved clarity and grammatical correctness.
Common error
Do not combine "but" with "because" in this way. "But" introduces a contrast, while "because" introduces a reason. Using them together creates a grammatically incorrect and confusing sentence. Rephrase to clearly separate the contrast and the reason.
