I'm quite new to WP and faced this problem on the website I have now. On my blog pages i have multiple warnings displayed on the sidebar. Seems it's broken and there's no relevant info I can currently find on the web. What's your advice?
Warning: Illegal string offset ‘tooltip_pos' in /home/letsstartagain/public_html/wp-content/themes/Avada/includes/class-fusion-widget-social-links.php on line 24
Whenever you see errors like that, there are clues as to what is causing the problem. In this case, as you read the link of text, the error points to the Avada theme, which appears to be the theme you are using. With that info you can go to the Avada developer for support.
The Avada theme is not one I recommend to people because it's not a well coded or fast theme.
