Unable to perform limited scan

    Hello,

    I modified the performance options to use the lowest ressources as possible but I’m unable to perform a scan of my website. The problem is that I have no idea why it fails but a simple message :

    Unable to perform limited scan […]

    In the options page I set memory usage for scaning to only 32 Mo and max execution time to 100. In my hosting PHP 7.3 configuration I have memory limit of 128 Mo and max execution time of 600000.

    So how can I investigate this problem?

    Here is my website

    Thanks!

  • Hey @frappi,

    Can you do the following so I can get the information I need to help you?

    Kill the existing scan if it is still running (The “Start New Scan” button turns in to a “Stop” button while the scan is running)

    Go to your Scan > Scan Options and Scheduling page and locate the “Performance Options”

    Set “Maximum execution time for each scan stage” to 20 on the options page
    Click to “Save Changes”

    Go to the Tools > Diagnostics page

    In the “Debugging Options” section check the circle “Enable debugging mode”
    Click to “Save Changes”.

    Start a new scan

    Copy the last 20 lines from the Log (click the “Show Log” link) or so of the activity log and paste them here

    Thanks,

    Looks like it is caused by a pluging called “Coming Soon Page & Maintenance Mode by SeedProd”. I disabled the feature in the plugin option, then I disactivated the plugin but problem was still here. After deleting completely the plugin the scan stop and fail for some reason.

    So I deleted the “all-in-one-wp-migration” and started a new scan but it failed again and again, now with the “litespeed-cache” plugin.

    What else can I do?

    I started another scan and noticed it passed the previous file img_optm.class.php until css_async.min.js, then it stopped and failed.

    Hey @frappi,

    It’s possible this is due to LiteSpeed server configuration. Can you please take a look at the article below and let me know if it helps?
