Support » Plugin: WordPress Gallery Plugin - NextGEN Gallery » Error while creating thumbnail

  • Resolved sgben


    Thumbnail doesnt generate. I have tried amending the max size for thumbnail but it doesn’t work. It occurs for two of my three images which are smaller in size as compared to the one which is successful.

    All I get is:

    “A failure occurred
    Error while creating thumbnail.
    ID 52: A failure occurred
    Error while creating thumbnail.”

    I have also tried ticking the checkbox for “Ignore aspect ratio”.

    Checked that no thumbnail was generated in the directory except for the biggest size image.

    Here’s my system config:

    Hi @sgben,

    Let’s first check to see if there is a plugin conflict happening. Temporarily deactivate all plugins, then reactivate NextGEN Gallery only. Does the issue still appear? If so, temporarily switch to a WordPress default theme (this deactivation is only intended to quickly check to see if the issue goes away or is still present). If by deactivating the other plugins the issue does go away, reactivate each of the other plugins one at a time to locate the culprit. Keep me posted on your results 🙂


    Same issue here but appears to be a browser error?


    Failed to load resource: net::ERR_SPDY_PROTOCOL_ERROR:

    Hi @rhlarson,

    Could you please try the same debugging steps listed in the message from above to see if that changes anything?

    Because it has been a month or more since your last reply, I am going to mark this as resolved as I assume you have found a solution. Please feel free to reply again if you still have questions. 🙂
