Troubleshooting common errors
Most “it just doesn’t work” moments on ArtHelper come from one of five causes — a browser extension, a stale page, a slow network, an expired Instagram connection, or an oversized file. This article walks through what to try first, second, and third before you contact support.
The five fixes that resolve most issues, in order
Refresh the page. Boring but it works more often than anything else. Press Ctrl+R (Windows) or Cmd+R (Mac), or click your browser’s refresh button.
Sign out, sign back in. Click your avatar in the top-right → Sign out, then sign in again at arthelper.com/signin. This fixes most stale-session issues.
Pause your browser extensions. Especially Pinterest, ad blockers, and privacy extensions. Sign-in cookies and image uploads break under aggressive blockers. The fastest test: open an Incognito / Private window and try again — extensions are off there by default. If it works in Incognito, you’ve found the culprit.
Try a different browser. Chrome, Safari, Firefox, and Edge all work. If the issue is browser-specific you’ll find out fast.
Try a different network. Switch from home wifi to your phone’s hotspot, or vice versa. Corporate and school networks sometimes block upload endpoints.
If steps 1–5 above don’t fix it, the issue is probably specific to one feature (upload, AI, Instagram) — see the targeted sections below.
”Upload failed” / “Something went wrong” when adding artwork
The two most common causes of upload failures:
The file is too big. The hard limit is 25 MB per image. Many phone photos in original quality are larger — open the image, save a smaller copy, and upload that.
The file is the wrong format. We accept JPG, PNG, WEBP, and HEIC. If you’re trying to upload a RAW file (.CR2, .NEF, .DNG, .ARW), Photoshop file (.PSD), or PDF, that won’t work. Export to JPG first.
If the file is the right size and format and uploads still fail:
Open an Incognito window and try the upload there — rules out an extension.
Try one image at a time instead of a bulk upload — narrows down whether it’s one bad file or all of them.
If only ONE specific image fails, save the image again in your photo editor with a slightly lower quality setting. Some files have corrupted metadata that breaks the upload.
AI generation is spinning forever
Title generation, description generation, and Sparks all use AI behind the scenes. When the spinner runs for more than ~30 seconds, something is off.
Refresh the page (Ctrl+R / Cmd+R). The job may have already completed but the page didn’t catch the update.
Try a different piece of artwork. If only ONE image hangs, that image may be corrupted or unreadable to the AI; re-save and re-upload.
Try again in 30 seconds. AI generation is one of the rare areas where load spikes can slow things down. A retry usually works.
If every generation hangs across every piece, contact support — it’s a service issue and we want to know.
Instagram post failed
The most common cause of an Instagram post failure is an expired connection. Tokens last about 60 days; after that you have to reconnect.
Find Instagram in the list. If the status is Disconnected or shows an error, click Reconnect.
Go through the Meta sign-in flow again. Make sure you pick the same Instagram account you had before.
Try posting again from app.arthelper.ai/post.
If reconnecting doesn’t fix it, the second most common cause is that your Instagram account is set as Personal instead of Business or Creator. Meta’s API only allows posts from Business or Creator accounts. In the Instagram mobile app: Settings → Account → Switch to Professional.
The page won’t load — just shows “Loading…” forever
Refresh the page.
Check your internet — open another site to confirm.
Try Incognito mode. If it loads there, an extension is the cause.
Try a different browser. Sometimes a corrupted browser profile breaks just one site.
If the page works on your phone but not your computer (or vice versa), the issue is local — see the five fixes above.
Common questions
I’m getting the same error every time and nothing fixes it. Now what?
Take a screenshot of the error (including any code or message), note exactly what you were trying to do when it happened, and contact support via the chat icon in the bottom-right of any ArtHelper page. The more specific you can be, the faster we can find the cause.
The “chat” or “Assistant” button doesn’t do anything when I click it.
Usually a browser extension blocking the chat window. Open Incognito and try again — if it opens, an extension is the cause. If it still doesn’t open in Incognito, refresh once and try again.
I see a “500” or “503” error code on the page.
That’s a temporary server issue, not something on your side. Wait 1–2 minutes and refresh. If it persists beyond ten minutes, contact support — we may not yet be aware of an outage.
Why is my page slow but not actually broken?
Often a browser cache that’s gotten too big. In Chrome: Settings → Privacy → Clear browsing data → Cached images and files. This doesn’t sign you out and doesn’t lose any of your artwork — it just frees up memory.
I can’t find the answer here. How do I reach a human?
Click the chat icon in the lower-right corner of any ArtHelper page. A real person will reply within one business day, often much sooner.
