Hi there chulapopop. Thanks for the note and sorry to hear about the inconvenience. Are you saying that the whole sidebar is missing, or just the plugins specific to The Events Calendar? Assuming it’s the first of these hypotheses…you should be able to tweak that by selecting a different template option under Events -> Settings -> Template. Can you try out each of the options in the dropdown there and let me know if you’re unable to find one that meets your needs?
