i’ve built a test page and closed in on the problem. Any [wptabs] located AFTER a [wptabs mode=”vertical”] will break.
Example:
[wptabs]
[wptabtitle] Tab 1[/wptabtitle]
[wptabcontent] This is the content of Tab1.[/wptabcontent]
[wptabtitle] Tab 2 [/wptabtitle]
[wptabcontent] This is the content of Tab2[/wptabcontent]
[/wptabs]
[wptabs mode="vertical"]
[wptabtitle] Tab 1[/wptabtitle]
[wptabcontent] This is the content of Tab1.[/wptabcontent]
[wptabtitle] Tab 2 [/wptabtitle]
[wptabcontent] This is the content of Tab2[/wptabcontent]
[/wptabs]
[wptabs mode="vertical"]
[wptabtitle] Tab 1[/wptabtitle]
[wptabcontent] This is the content of Tab1.[/wptabcontent]
[wptabtitle] Tab 2 [/wptabtitle]
[wptabcontent] This is the content of Tab2[/wptabcontent]
[/wptabs]
The top 2 tabs will work, but the one after the mode=vertical on will break…
