On my website www.agustipardo.es, I have a Slider Revolution presentation on the homepage. I have the Litespeedcache plugin installed, and when I analyze the website with pagespeed.web.dev, I get the following warning:
Displayed size 400x267, Real size 1x1, Expected size 600x401.
The source of the problem appears to be a file generated by Revolution Slider called ‘dummy.png.’ Can you tell me if this is the case, what it’s used for, and what I can do to prevent this error detected by pagespeed.web.dev?
Sometimes, if somone offers code for free, they like to keep track of who’s using it, so they insert a tiny 1x1 pixel image into the code that links back to their site. That way, they can get a sense of where their script is being used by tracking requests for that tiny file.
I don’t know if that’s the case here, but personally, I would track down the link to that image in the code an remove it.
I am also face this issue in few days ago in my website but I upload another image and my issue is solved. you try once upload other image then see what happen
Hey @ralphm@argosbcn i am stuck in the same issue: i created a slide in Slide Revolution and obtained the static file via Simply Static (plugin) : the folder downloaded doesn’t contain neither the svg,png or jpg that i uploaded, and that are present on localWP’s developing wordpress instance, but instead an empty dummy.png at “wp-content/plugins/revslider/public/assets/assets/dummy.png”.
I noticed that if i set - Global Settings/Modules Optimization/Default lazy loading in modules - to “All” or “No Change”, as in https://69e8dfc1.testwp123.pages.dev/ , i get Uncaught TypeError: Failed to execute ‘serializeToString’ on ‘XMLSerializer’: parameter 1 is not of type ‘Node’.
and
“/wp-content/uploads/revslider/svg/objects/svgcustom/MASTRO_1.svg Could not be loaded !” : it doesn’t include the svg .
Otherwise the dummy.png appears if i set Global Settings/Modules Optimization/Default lazy loading in modules - to “Smart” : i also get the effect that neither the png or jpg are shown, along side with the svg , as shown in https://5827feec.testwp123.pages.dev …
Is there anyone with a licensed Revolution Slider who could post the question in the plugin’s support forum? I tried reaching out to them, but essentially, they told me that if I wanted support, I had to purchase the license. I don’t mind paying for plugins I’ll use; in fact, I’ve purchased the pro version of RankmathSEO. However, it seems unfair to pay for features I won’t use just to access some support.
Providing free support only for paid versions of a plug-in or app is standard practice. Does it seem fair to you that the developer should not only provide the results of his/her work, but also spend time giving free support to those who don’t consider that work worth paying for? Developers need to live, just like anyone else, and they are entitled to earn from their work.
Support on the forums here is free, because they are volunteer-run and members give up their own time to help others, but that doesn’t mean it’s typical of support arrangements.
There are many plugins that offer support even with a free version and a paid version. While I don’t expect the developer to dedicate a significant amount of time to solving my issues, it’s also a quid pro quo to identify potential problems or provide ideas for improving the plugin. Developers can make a good living through plugin development and selling pro features. Slider Revolution, with 9 million users at 35 euros per year for the cheapest subscription and 1999 euros for a 100-site subscription, doesn’t provide any support. On the other hand, RankmathSEO and Litespeedcache, also large plugins, offer free support regardless of the pro version. This ensures users aren’t excluded, forced to pay for features they may not need. Let’s stick to the main topic and avoid going off-topic on WordPress plugin support, shall we?
