Several trouble after updating

    Hello,

    I am having some issues since last update I made.

    First of all, some students are active enrolled, but when tried to access they received message informing that they are not enrolled.
    Those courses do not have any kind of expiration date or something like that.
    I already clear cache from inside the website. I told them to clean their own cache.
    When I access they’re panel to test it, I am able to access the courses. However they can’t. Every day more and more students are complaining about that.

    Other problem refers to editing classes content. Where I already had some content is not showing.

    Hello @thomasplevy

    Could you please let me know if you are still trying to make it worked out on SiteGround?
    My issues continued the same. So, please, let me know if you’re still looking for it.
    Otherwise I will try to migrate the hole site to a different hosting.

    Thank you

    After a really extensive review we’ve found that the only issue we can find is that when *deactivating* the SG Optimizer plugin the .htaccess rules which are added for the browser caching setting are not removed.

    This isn’t really a bug. It makes sense that it works this way. Perhaps SG could change the behavior but it’s pretty common for plugins to not automatically change things (like removing data from the database) during a deactivation incase it’s just being temporarily deactivated for debugging purposes.

    So the solution is to not disable the plugin but to disable browser caching. @d4z_c0nf posted a solution to this on page 3 of this thread.

    The issues you have reported are recreatable when browser caching is enabled. Once it’s disable the issues go away.

    This isn’t a bug in either system. Browser caching *stores the rendered HTML of the page* in the visitors browser and uses that for subsequent visits. Disabling this prevents that from happening.

    It’s complicated to turn this off from within LifterLMS conditionally as it’s something that gets handled by Apache (your webserver). So you *must* disable this when using LifterLMS.

    LifterLMS is highly dynamic. It’s NOT a static blog which you can serve the same thing to every user.

    Outside of that I don’t have any idea what else we can do. We’ve gotten this fixed for a number of users by taking these steps.

    Does that help?

    Hello @thomasplevy thank you for your response.

    I understand.
    So… yes, I had disabled browser caching.
    Let me show you the settings I currently have on SG Optmizer:

    https://ibb.co/c1b5zBG

    https://ibb.co/Qmkv4MD
    Is it everything correct? Is something I should turn off?

    Thank you.

    @0rbita

    That all looks correct to me.

    If your students are still seeing error messages and cached content when they’re logged in you’re really going to need to work with SiteGround to determine why they’re still being served cached content when they’re not supposed to be.

    LifterLMS is *not* malfunctioning here. We have exhaustively researched this issue and found that it only appears to malfunction when browser caching is enabled and that results in the users being served cached pages. Nothing is BROKEN. It’s just an incompatibility (or maybe better a paradox). A user cannot get dynamic restricted content AND be served a cached page simultaneously.

    If you’re using other caching mechanisms on top of the SG Optimizer you’ll want to look into having those disabled (at least temporarily) also.

    Services like CloudFlare could also be caching HTML pages on your behalf. You can still use CloudFlare (or services like it) but if you have it serve fully cached pages you’ll have the exact same problem you’re describing.

    I really am at a loss as to what else we can do for you. We’ve identified a problem and provided steps to resolve it and if that’s not working for you I don’t know what else to say or how else to help.
