When using Midjourney, the most frustrating thing isn’t slow image generation, but prompts suddenly getting rejected, content being blocked, or errors popping up as soon as you enter parameters. Below is a troubleshooting guide organized around the three most common problem types, helping you quickly identify whether the failure is caused by the prompt, an image link, or parameter formatting. Follow the steps and you can usually get back to generating images normally within minutes.
Prompt Rejected: Start by Breaking Down “Sensitive Triggers”
When Midjourney displays something like “prompt rejected/flagged,” the first thing to do is remove the parts of the prompt most likely to trigger moderation and try again: explicit sexual descriptions, gory/violent details, anything involving minors, hate or attacks, explicit references to real people, etc. Often it’s not that the whole prompt is unacceptable—one particular phrase triggers the block. For Midjourney troubleshooting, you need to learn the “binary search” approach: delete or rewrite sections step by step to pinpoint the culprit.
In practice, keep the subject and setting first, strip out adjectives and fine details, then add them back gradually; replacing blunt wording with more neutral expressions is also more reliable. If you’re aiming for a brand or character style, focus on describing “clothing, lighting, camera, materials,” and avoid direct, referential phrasing like “looks like so-and-so,” which is more likely to be blocked.
Moderation Block: Why the “Same Sentence” Sometimes Passes and Sometimes Doesn’t
Midjourney’s moderation doesn’t always produce a fixed outcome: the same theme, with different wording or different intensity of detail, may pass once and get blocked another time. When troubleshooting, it’s recommended to “lower the risk level” of high-risk elements: reduce the degree of violence, avoid nudity and borderline sexual suggestions, and change conflict scenes into more abstract expressions such as “a tense atmosphere in a movie-poster style.”
If you trigger blocks repeatedly, pause before trying again to avoid submitting similar content many times in a short period. You can also start with a safer base prompt to confirm the workflow works, then add details gradually to identify which part triggers the moderation block.
