When I installed the upgrade to 4.1.8 (from 4.1.7) the title line for comments showed text like this: {_JOOMLACOMMENT_ADDNEW} {_JOOMLACOMMENT_SEARCH} {_JOOMLACOMMENT_RSS} . I fixed it by editing the HTML file and replaced these with words that made sense to the user. I know very little about PHP but I presume these call words that vary with the language used. The search function also had the same issue but I ended up removing the link to the search function. That was because a search did not work - it came up with a string of error messages. No problem, I don't particularly want to allow comment search anyway.
Is there a problem with my installation or upgrade? It seemed to install OK.
