Since Magento is a robust system used for building websites, you can use it for building super – mega e-commerce websites. The caching solution has been implemented. Magento does focus caching thus significantly improving the load speed on a website. And we all know how important it is to have fast loading pages, especially in the e-commerce industry. This will enable customers to have an excellent shopping experience and prevent card and store abandonment.
But what if something goes wrong and you experience specific malfunctions such as an extension crashing that takes more page load times spiking, etc. So let’s see some of the most common problems related to Magento caching and at the same time how to troubleshoot them.
Common Caching Problems –
Before we start, I recommend you to make sure to revise your knowledge on all types of Magento caches. You are making adjustments on your e-commerce website and the changes that you make are not apparent. This is a result of an enabled cache you have to disable that during development so that all changes you make become visible at that very moment.
Access system caching management and then select page cache and disable it from the drop-down menu on the right.
You have updated CMS pages or you have added, changed some new content buttons, not a single one of your actions are visible on the website.
Now it has happened due to a cache problem and you must need to clear it with admin rights. You can do it easily by accessing system cache management, selecting the page cache and choosing refresh from the drop-down menu on the top right.
Avoid installing and using extensions that don’t provide information on how to configure your caching and how to fix Magento caching. So the e-commerce websites are very big and contain more than 50 extensions. This very often causes a page simply back after enabling page cached.
Cache – the most common reason that causes errors with cache is an extension that inserts content on pages for specifically defined customer groups. Whenever you encounter a problem, always start from there. It is a common mistake which is generally observed when troubleshooting is, to test only one type of customer, log out and clears the cache. Troubleshooting has to be done when all types of customers are browsing the e-commerce website at the same time.
In the end, we all know how troubleshooting is painful and time-consuming, in order to see what is causing the problem on a live website. Start disabling each cache option in order to identify which one of them is causing the problem when enabled, only after doing so; you will be able to reach a solution.
Here are some of the best practices to avoid Magento cache problems in order to minimize the risks of getting problems which are related to the cache. So make sure to implement these best practices when building or maintaining a Magento powered e-commerce website.
At the start, you want to make sure to configure your full – page cache auto-generation in order to avoid it over creating restrictions cache slow page loading times.
You can do this by accessing the full – page cache panels via system- configuration system menu. In this panel you want to add value for cache – lapse time after this time the value is added in minutes, by the way, all the cache from that visitor session would be removed, when visitors come back again.
The cache is going to be recreated. Also, make sure to limit the number of cached files that are to be stored. You can do this by setting the value for the maximum allowed page value here. You can see the number of parameters that will determine if the pages are going to be cached at all. You can also set Magento to cache only the pages with the default currency.
You should really consider this if you have stores that support dozens of currencies and this cache can significantly affect your e-commerce website performance.
The option is found in the same panel at the above 2 and it is labeled as enabling cache for not default currencies. Make sure to enable caching a moment for getting Magento out of the box. This will allow you to test the extension by extension value you are implementing them. And quickly identify the one that causes the problem.
I hope you have learned something about how to troubleshoot Magento caching problems. So if you are a Magento developer then make sure to apply the above – mentioned best practices so as to avoid the problems later on and also make sure to stay updated, though Magento community is huge and willingly shares the solutions to common problems as well as ultra-specific tips and tricks.
