    When I attempt to download the latest version of the power add-on, SLP-Power.Zip 4.8.62017-11-19, I receive the following error message:  “Decompression Failed”.  I would appreciate if you would look into this at your earliest convenience.


    Where are you seeing that error message?


    I am seeing the error message on the Downloads page (  A screenshot is attached for your reference.

    I attempted the download without success in Safari, Chrome and IE.  If my memory serves me correctly, downloads for previous versions saved to my local drive as unzipped folders.  For some reason the latest update is saving as an unreadable zip file.  When I attempt to upload the file to WordPress, I receive the following error message:  “The package could not be installed. PCLZIP_ERR_BAD_FORMAT (-10) : Unable to find End of Central Dir Record signature”.  A screenshot of this error is also attached for your review.

    I am getting this too, but on a Mac.

    MACHINE NAME:project_slp patrik$ unzip
    End-of-central-directory signature not found.  Either this file is not a zipfile, or it constitutes one disk of a multi-part archive.  In the latter case the central directory and zipfile comment will be found on
    the last disk(s) of this archive.
    unzip:  cannot find zipfile directory in one of or, and cannot find, period.

    In short; the zip-file is broken.


    Thank you for notifying us I have identified the issue and notified the Developer, he is travelling today and will look into this tonite or tomorrow as soon as he can access his developer tools and computer.


    Hello ALL,

    try it now, the developer fixed the compression file while at the rest area. 

    ​i was lucky to catch him while he wasn’t driving . He was working while on his mini holiday and the internet service stopped in the middle of some updates thus causing this error.


    thanks to you guys, I decided to delete and re-install Power since i could not recreates the issue. this gave us some useful clues as to when this may have happened since there was no issue before.


    P.S.  The next release of SLP and Power will be 4.9 to be published some time in the next few days. He will let us know via changelog if this effects anyone using the new WP 4.9.

    Thanks again for your patience and sorry for the inconveninece
