Hey Roidney,
Real sorry to hear about your problems here, let’s see what we can do to sort this out – the first step in that direction is to address the general situation when you try to update the translation files. For example, this file:
public_html/wp-content/languages/admin-es_ES.mo
Is not a file generated by or related to The Events Calendar.
So there may be something else going on with your site here. To help iron out the scope of your problem, can you address each of the following items in the order they appear?
1. You say, “When I installed the plug-in I’m getting an error:” – What do you mean by this, exactly? Do you mean that you upload The Events Calendar to your site, click “Activate”, and then this error just shows up? Or do you mean updating WordPress itself? Or something else altogether?
2. You say, “I have uninstalled it and reinstalled it a couple of times with the same results.” – What version of The Events Calendar are you using?
3. What version of WordPress is your site running?
Thank you!
George
